Package 'TAF'

Description

General framework to organize data, methods, and results used in reproducible scientific analyses. A TAF analysis consists of four scripts (⁠data.R⁠, ⁠model.R⁠, ⁠output.R⁠, ⁠report.R⁠) that are run sequentially. Each script starts by reading files from a previous step and ends with writing out files for the next step.

Convenience functions are provided to version control the required data and software, run analyses, clean residues from previous runs, manage files, manipulate tables, and produce figures. With a focus on stability and reproducible analyses, the TAF package comes with no dependencies.

TAF forms a base layer for the icesTAF package and other scientific applications.

Description

Compare versions declared in ⁠SOFTWARE.bib⁠ with packages installed in the global R library.

Usage

check.software(full = FALSE)

Arguments

Value

Logical vector (or data frame if ⁠full = TRUE⁠) indicating which installed packages are ready, i.e., at least as new as the version required in ⁠SOFTWARE.bib⁠.

A warning is raised if any installed packages are older than required.

Note

Generally, TAF installs R packages that are declared in ⁠SOFTWARE.bib⁠ inside the TAF library (⁠boot/library⁠). This guarantees that the right versions of packages are installed for the analysis. The taf.library function is then used to load packages from the TAF library.

In special cases, however, it might be useful to compare the versions of packages declared in ⁠SOFTWARE.bib⁠ against packages that are installed in the global R library, outside the TAF library.

See Also

taf.boot and taf.library are the general tools to install and load packages of the correct version in the TAF library.

update.packages can be used to update packages in the general R library to the newest version available on CRAN.

Examples

## Not run: 
check.software()
check.software(full=TRUE)

## End(Not run)

Description

Remove TAF directories: ⁠data⁠, ⁠model⁠, ⁠output⁠, and ⁠report⁠.

Usage

clean(dirs = c("data", model.dir(), "output", "report"), force = FALSE)

Arguments

Details

The ⁠model⁠ directory may also be named ⁠method⁠ and is cleaned in the same way.

Value

No return value, called for side effects.

Note

The purpose of removing the directories is to make sure that subsequent TAF scripts start by creating new empty directories.

If any of the dirs is "boot", it is treated specially and clean.boot is called to clean the ⁠boot⁠ directory.

In other words, clean("boot") and clean.boot() are interchangeable, the latter providing a slightly clearer interface that was introduced in version 4.2.0.

See Also

clean.boot cleans the boot directory.

mkdir and rmdir create and remove empty directories.

TAF-package gives an overview of the package.

Examples

## Not run: 
clean()
clean.boot()

## End(Not run)

Description

Clean the boot directory using clean.data, clean.library, and clean.software.

Usage

clean.boot(force = FALSE)

Arguments

Value

No return value, called for side effects.

Note

Instead of completely removing the ⁠boot⁠ directory, clean.data, clean.library, and clean.software are used to clean the ⁠boot/data⁠, ⁠boot/library⁠, and ⁠boot/library⁠ subdirectories. This protects the subdirectory ⁠boot/initial⁠, boot scripts, and ⁠*.bib⁠ metadata files from being accidentally deleted.

See Also

clean cleans TAF directories: ⁠data⁠, ⁠model⁠, ⁠output⁠, and ⁠report⁠.

clean.data selectively removes data from ⁠boot/data⁠.

clean.library selectively removes packages from ⁠boot/library⁠.

clean.software selectively removes software from ⁠boot/software⁠.

TAF-package gives an overview of the package.

Examples

## Not run: 
clean()
clean.boot()

## End(Not run)

Description

Selectively remove data from the ⁠boot/data⁠ folder if not listed in ⁠DATA.bib⁠.

Usage

clean.data(folder = "boot/data", quiet = FALSE, force = FALSE)

Arguments

Value

No return value, called for side effects.

Note

For each data file or subfolder, the cleaning procedure selects between two cases:

1. Data entry found in ⁠DATA.bib⁠ - do nothing.

2. Data entry is not listed in ⁠DATA.bib⁠ - remove.

The taf.boot procedure cleans the ⁠boot/data⁠ folder, without requiring the user to run clean.data.

See Also

taf.boot calls clean.data as part of the default boot procedure.

clean.software cleans the local TAF software folder.

clean.library cleans the local TAF library.

TAF-package gives an overview of the package.

Examples

## Not run: 
clean.data()

## End(Not run)

Description

Selectively remove packages from the local TAF library if not listed in ⁠SOFTWARE.bib⁠.

Usage

clean.library(folder = "boot/library", quiet = FALSE, force = FALSE)

Arguments

Value

No return value, called for side effects.

Note

For each package, the cleaning procedure selects between three cases:

1. Installed package matches ⁠SOFTWARE.bib⁠ - do nothing.

2. Installed package is not the version listed in ⁠SOFTWARE.bib⁠ - remove.

3. Installed package is not listed in ⁠SOFTWARE.bib⁠ - remove.

The taf.boot procedure cleans the TAF library, without requiring the user to run clean.library. The main reason for a TAF user to run clean.library directly is to experiment with installing and removing different versions of software without modifying the ⁠SOFTWARE.bib⁠ file.

See Also

taf.boot calls clean.library as part of the default boot procedure.

taf.install installs a package in the local TAF library.

clean.software cleans the local TAF software folder.

clean.data cleans the ⁠boot/data⁠ folder.

TAF-package gives an overview of the package.

Examples

## Not run: 
clean.library()

## End(Not run)

Description

Selectively remove software from the local TAF software folder if not listed in ⁠SOFTWARE.bib⁠.

Usage

clean.software(folder = "boot/software", quiet = FALSE, force = FALSE)

Arguments

Value

No return value, called for side effects.

Note

For each file (and subdirectory) in the software folder, the cleaning procedure selects between three cases:

1. File and version matches ⁠SOFTWARE.bib⁠ - do nothing.

2. Filename does not contain the version listed in ⁠SOFTWARE.bib⁠ - remove.

3. File is not listed in ⁠SOFTWARE.bib⁠ - remove.

The taf.boot procedure cleans the TAF software folder, without requiring the user to run clean.software. The main reason for a TAF user to run clean.software directly is to experiment with installing and removing different versions of software without modifying the ⁠SOFTWARE.bib⁠ file.

See Also

taf.boot calls clean.software as part of the default boot procedure.

download.github downloads a GitHub repository.

clean.library cleans the local TAF library.

clean.data cleans the ⁠boot/data⁠ folder.

TAF-package gives an overview of the package.

Examples

## Not run: 
clean.software()

## End(Not run)

Description

Convert spaces in filenames.

Usage

convert.spaces(file, sep = "_")

Arguments

Value

TRUE for success, FALSE for failure, invisibly.

Note

This function treats ‘%20’ in filenames as a space and converts to sep.

See Also

file.rename is the base function to rename files.

TAF-package gives an overview of the package.

Examples

## Not run: 
write(pi, "A B.txt")
convert.spaces("A B.txt")

# Many files
convert.spaces("boot/initial/data/*")

## End(Not run)

Description

Copy or move files, overwriting existing files if necessary, and returning the result invisibly.

Usage

cp(from, to, move = FALSE, ignore = FALSE, overwrite = TRUE,
  quiet = TRUE)

Arguments

Value

TRUE for success, FALSE for failure, invisibly.

Note

To prevent accidental loss of files, two safeguards are enforced when move = TRUE:

1. When moving files, the to argument must either have a filename extension or be an existing directory.

2. When moving many files to one destination, the to argument must be an existing directory.

If these conditions do not hold, no files are changed and an error is returned.

See Also

file.copy and unlink are the underlying functions used to copy and (if move = TRUE) delete files.

file.rename is the base function to rename files.

TAF-package gives an overview of the package.

Examples

## Not run: 
write(pi, "A.txt")
cp("A.txt", "B.txt")
cp("A.txt", "B.txt", move=TRUE)

# Copy directory tree
cp(system.file(package="datasets"), ".")
mkdir("everything")
cp("datasets/*", "everything")

## End(Not run)

Description

Show the data dimensions of a table.

Usage

ddim(x, reduce = FALSE)

Arguments

Details

Dimension variables can include year, age, region, fleet, survey, or the like, generally an integer or string. The measurement variable can be catch, fishing mortality, maturity, weight, or the like, often a decimal.

x can also be an FLR table in FLQuant format.

Value

Named vector showing the dimension names and number of levels.

See Also

unique is the base function to extract the levels of a dimension variable.

TAF-package gives an overview of the package.

Examples

# Long table format, 8 years and 4 ages
ddim(catage.long)

# Some base R datasets
ddim(esoph[-5])
ddim(rev(warpbreaks))
ddim(rev(ToothGrowth))

Description

Search R scripts for packages that are required.

Usage

deps(path = ".", base = FALSE, installed = TRUE, available = TRUE,
  list = FALSE)

Arguments

Details

The files analyzed are those with the file extensions .R, .r, .Rmd, and .rmd.

Value

Names of packages as a vector, or in list format if list=TRUE. If no dependencies are found, the return value is NULL.

Note

Package names are matched based on four patterns:

library(*)
require(*)
*::object
*:::object

The search algorithm may return false-positive dependencies if these patterns occur inside if-clauses, strings, comments, etc.

See Also

installed.packages, available.packages.

TAF-package gives an overview of the package.

Examples

## Not run: 
dir <- system.file(package="MASS", "scripts")
script <- system.file(package="MASS", "scripts/ch08.R")

deps(script)                   # dependencies
deps(script, base=TRUE)        # including base packages
deps(script, installed=FALSE)  # not (yet) installed

deps(dir)
deps(dir, list=TRUE)

deps(dir, available=FALSE)  # dependencies that might be unavailable

## End(Not run)

Description

Detach all non-base packages that have been attached using library or taf.library.

Usage

detach.packages(quiet = FALSE)

Arguments

Value

Names of detached packages.

See Also

detach is the underlying base function to detach a package.

taf.library loads a package from ⁠boot/library⁠.

TAF-package gives an overview of the package.

Examples

## Not run: 
detach.packages()

## End(Not run)

Description

Divide column values in a data frame with a common number.

Usage

div(x, cols, by = 1000, grep = FALSE, ...)

Arguments

Value

A data frame similar to x, after dividing columns cols by the number by.

Note

Provides notation that is convenient for modifying many columns at once.

See Also

transform can also be used to recalculate column values, using a more general and verbose syntax.

grep is the underlying function used to match column names if grep is TRUE.

rnd is a similar function that rounds columns.

TAF-package gives an overview of the package.

Examples

# These are equivalent:

x1 <- div(summary.taf, c("Rec","Rec_lo","Rec_hi",
                         "TSB","TSB_lo","TSB_hi",
                         "SSB","SSB_lo","SSB_hi",
                         "Removals","Removals_lo","Removals_hi"))

x2 <- div(summary.taf, "Rec|TSB|SSB|Removals", grep=TRUE)

x3 <- div(summary.taf, "Year|Fbar", grep=TRUE, invert=TRUE)

# Less reliable in scripts if columns have been added/deleted/reordered:

x4 <- div(summary.taf, 2:13)

Description

Convert line endings in a text file between Dos (CRLF) and Unix (LF) format.

Usage

dos2unix(file, force = FALSE)

unix2dos(file, force = FALSE)

Arguments

Details

The default value of force = FALSE is a safety feature that can avoid corrupting files that are not standard text files, such as binary files. A standard text file is one that can be read using readLines without producing warnings.

Value

No return value, called for side effects.

See Also

line.endings examines line endings.

TAF-package gives an overview of the package.

Examples

## Not run: 
file <- "test.txt"
write("123", file)

dos2unix(file)
file.size(file)

unix2dos(file)
file.size(file)

file.remove(file)

## End(Not run)

Description

Download a file in binary mode, e.g. a model executable.

Usage

download(url, dir = ".", mode = "wb", chmod = file_ext(url) == "",
  destfile = file.path(dir, basename(url)), quiet = TRUE, ...)

Arguments

Details

With the default mode "wb" the file is downloaded in binary mode (see download.file), to prevent R from adding ⁠^M⁠ at line ends. This is particularly relevant for Windows model executables, while the chmod switch is useful when downloading Linux executables.

This function can be convenient for downloading any file, including text files. Data files in CSV or other text format can also be read directly into memory using read.table, read.taf or similar functions, without writing to the file system.

Value

No return value, called for side effects.

Note

If destfile contains a question mark it is removed from the destfile filename. Similarly, if destfile contains spaces or ‘%20’ sequences, those are converted to underscores.

In general, TAF scripts do not access the internet using download or similar functions. Instead, data and software are declared in DATA.bib and SOFTWARE.bib and then downloaded using taf.boot. The exception is when a boot script is used to fetch files from a web service (see TAF Wiki).

See Also

download.file is the underlying base function to download files.

download.github downloads a GitHub repository.

TAF-package gives an overview of the package.

Examples

## Not run: 
url <- paste0("https://github.com/ices-taf/2015_had-iceg/raw/master/",
              "bootstrap/initial/software/catageysa/catageysa.exe")
download(url)

## End(Not run)

Description

Download a repository from GitHub in ‘tar.gz’ format.

Usage

download.github(repo, dir = ".", quiet = FALSE)

Arguments

Value

Name of downloaded ⁠tar.gz⁠ file.

Note

In general, TAF scripts do not access the internet using download.github or similar functions. Instead, data and software are declared in ⁠DATA.bib⁠ and ⁠SOFTWARE.bib⁠ and then downloaded using taf.boot. The exception is when a boot script is used to fetch files from a web service (see TAF Wiki).

See Also

taf.boot uses download.github to fetch software and data repositories.

download downloads a file.

untar extracts a ⁠tar.gz⁠ archive.

taf.install installs a package in ⁠tar.gz⁠ format.

TAF-package gives an overview of the package.

Examples

## Not run: 
# Specify release tag
download.github("ices-tools-prod/[email protected]")

# Specify SHA reference code
download.github("ices-tools-prod/icesAdvice@4271797")

## End(Not run)

Description

Create an initial draft version of a ‘DATA.bib’ metadata file.

Usage

draft.data(originator = NULL, year = format(Sys.time(), "%Y"),
  title = NULL, period = NULL, access = "Public", source = NULL,
  file = "", append = FALSE,
  data.files = dir(taf.boot.path("initial/data")),
  data.scripts = dir(boot.dir(), pattern = "\\.R$"))

Arguments

Details

Typical usage is to specify originator, while using the default values for the other arguments. Most data files have the same originator, which can be specified to facilitate completing the entries after creating the initial draft.

The data access codes come from https://vocab.ices.dk/?ref=1435.

The special values ⁠source = "file"⁠, ⁠source = "folder"⁠, and ⁠source = "script"⁠ are described on the TAF Wiki, along with other metadata information.

The default value file = "" prints the initial draft in the console, instead of writing it to a file. The output can then be pasted into a file to edit further, without accidentally overwriting an existing metadata file.

Value

Object of class ⁠Bibtex⁠.

Note

This function is intended to be called from the top directory of a TAF analysis. It looks for data files inside ⁠boot/initial/data⁠ folder and data scripts inside ⁠boot⁠.

After creating the initial draft, the user can complete the description of each data entry inside the ⁠title⁠ field and look into each file to specify the ⁠period⁠ that the data cover.

See Also

period pastes two years to form a period string.

draft.software creates an initial draft version of a ⁠SOFTWARE.bib⁠ metadata file.

taf.boot reads and processes metadata entries.

TAF-package gives an overview of the package.

Examples

## Not run: 
# Print in console
draft.data("WGEF", 2015)

# Export to file
draft.data("WGEF", 2015, file=TRUE)

# Empty entry, to complete by hand
draft.data(data.files="")

## End(Not run)

Description

Create an initial draft version of a ‘SOFTWARE.bib’ metadata file.

Usage

draft.software(package, author = NULL, year = NULL, title = NULL,
  version = NULL, source = NULL, file = "", append = FALSE)

Arguments

Details

Typical usage is to specify package, while using the default values for the other arguments.

If package is an R package, it can either be a package that is already installed ("icesAdvice") or a GitHub reference ("ices-tools-prod/icesAdvice@4271797").

With the default ⁠version = NULL⁠, the function will automatically suggest an appropriate version entry for CRAN packages, but for GitHub packages it is left to the user to add further information about the GitHub branch (if different from ⁠master⁠) and the commit date.

With the default ⁠source = NULL⁠, the function will automatically suggest an appropriate source entry for CRAN and GitHub packages, but for other R packages it is left to the user to add information about where the software can be accessed.

The default value file = "" prints the initial draft in the console, instead of writing it to a file. The output can then be pasted into a file to edit further, without accidentally overwriting an existing metadata file.

Value

Object of class ⁠Bibtex⁠.

Note

After creating the initial draft, the user can complete the ⁠version⁠, ⁠source⁠, and other fields as required.

This function is especially useful for citing exact versions of R packages on GitHub. To prepare metadata for software other than R packages, see the TAF Wiki for an example.

See Also

citation and packageDescription are the underlying functions to access information about installed R packages.

draft.data creates an initial draft version of a ⁠DATA.bib⁠ metadata file.

taf.boot reads and processes metadata entries.

TAF-package gives an overview of the package.

Examples

# Print in console
draft.software("TAF")


## Not run: 
# Export to file
draft.software("TAF", file=TRUE)

## End(Not run)

Description

Examine file encoding.

Usage

file.encoding(file)

Arguments

Value

"latin1", "UTF-8", "unknown", or NA.

This function requires the file shell command to be in the path. Otherwise, this function returns NA.

Note

The encoding "unknown" indicates that the file is an ASCII text file or a binary file.

In TAF, text files that have non-ASCII characters should be encoded as UTF-8.

If this function fails in Windows, the guess_encoding function in the readr package may help.

See Also

Encoding examines the encoding of a string.

latin1.to.utf8 converts files from ⁠latin1⁠ to ⁠UTF-8⁠ encoding.

line.endings examines line endings.

TAF-package gives an overview of the package.

Examples

## Not run: 
file.base <- system.file(package="base", "DESCRIPTION")
file.nlme <- system.file(package="nlme", "DESCRIPTION")
file.encoding(file.base)  # ASCII
file.encoding(file.nlme)

## End(Not run)

Description

Convert a table from FLR format to TAF format.

Usage

flr2taf(x, colname = "Value")

Arguments

Value

A data frame in TAF format.

Note

FLR uses the FLQuant class to store tables as 6-dimensional arrays, while TAF tables are stored as data frames with a year column.

See Also

catage.taf describes the TAF format.

as.data.frame is a method provided by the FLCore package to convert FLQuant tables to a 7-column long format.

TAF-package gives an overview of the package.

Examples

x <- array(t(catage.xtab), dim=c(4,8,1,1,1,1))
dimnames(x) <- list(age=1:4, year=1963:1970,
                    unit="unique", season="all", area="unique", iter=1)
flr2taf(x)

x1 <- x[1,,,,,,drop=FALSE]
flr2taf(x1)
flr2taf(x1, "Juveniles")

Description

Look up SHA reference code on GitHub.

Usage

get.remote.sha(owner, repo, ref, seven = TRUE)

Arguments

Value

SHA reference code as a string.

See Also

taf.boot uses get.remote.sha to determine whether it is necessary to remove or download files, via clean.library, clean.software, and download.github.

TAF-package gives an overview of the package.

Examples

## Not run: 
get.remote.sha("ices-tools-prod", "icesAdvice", "master")

## End(Not run)

Description

Check if ‘.tar.gz’ file is an R package.

Usage

is.r.package(targz, spec = NULL, warn = TRUE)

Arguments

Details

The only purpose of passing spec is to get a more helpful warning message if the file contents look like an R package nested inside a repository.

Value

Logical indicating whether targz is an R package.

Examples

## Not run: 
is.r.package("boot/software/SAM.tar.gz")

TAF scripts that will be run as needed are: ⁠utilities.R⁠, ⁠data.R⁠, ⁠model.R⁠, ⁠output.R⁠, and ⁠report.R⁠.

The ⁠model.R⁠ script may also be named ⁠method.R⁠ and is treated in the same way.

See Also

source runs any R script, source.taf is more convenient for running a TAF script, and source.all runs all TAF scripts.

make, make.taf, and make.all are similar to the source functions, except they avoid repeating tasks that have already been run.

TAF-package gives an overview of the package.

Examples

## Not run: 
make.all()

## End(Not run)

Description

Run a TAF script if the target directory is either older than the script, or older than the directory of the previous TAF step.

Usage

make.taf(script, ...)

Arguments

Value

TRUE or FALSE, indicating whether the script was run.

Note

Any underlying scripts are automatically included if they share the same filename prefix, followed by an underscore. For example, when determining whether a script ⁠data.R⁠ should be run, this function checks whether ⁠data_foo.R⁠ and ⁠data_bar.R⁠ have been recently modified.

See Also

source runs any R script, source.taf is more convenient for running a TAF script, and source.all runs all TAF scripts.

make, make.taf, and make.all are similar to the source functions, except they avoid repeating tasks that have already been run.

Examples

## Not run: 
make.taf("model.R")

## End(Not run)

Description

Create directory, including parent directories if necessary, without generating a warning if the directory already exists.

Usage

Arguments

Value

TRUE for success, FALSE for failure, invisibly.

See Also

dir.create is the base function to create a new directory.

rmdir removes an empty directory.

clean can be used to remove non-empty directories.

TAF-package gives an overview of the package.

Examples

rmdir("outer", recursive=TRUE)

## End(Not run)

Description

Show a message, as well as the current time.

Usage

msg(...)

Arguments

Value

No return value, called for side effects.

See Also

message is the base function to show messages, without the current time.

Examples

msg("script.R running...")

Description

Determine operating system name.

Usage

os()

os.linux()

os.macos()

os.windows()

os.unix()

Value

os returns the name of the operating system, typically "Linux", "Darwin", or "Windows".

os.linux, os.macos, os.unix, and os.windows return TRUE or FALSE.

Note

The macOS operating system identifies itself as "Darwin".

Both Linux and macOS are os.unix.

These shorthand functions can be useful when writing workaround solutions in platform-independent scripts.

See Also

Sys.info is the underlying function used to extract the operating system name.

TAF-package gives an overview of the package.

Examples

os()
os.linux()
os.macos()
os.unix()
os.windows()

Description

Paste two years to form a period string.

Usage

period(x, y = NULL)

Arguments

Details

If x is a vector or a data frame, then the lowest and highest years are used, and y is ignored.

If x is a matrix or data frame, this function looks for years in the first column. If the values of the first column do not look like years (four digits), then it looks for years in the row names.

Value

A string of the form "1990-2000".

Note

This function can be useful when working with draft.data.

See Also

paste is the underlying function to paste strings.

draft.data has an argument called period.

TAF-package gives an overview of the package.

Examples

period(1963, 1970)
period(c(1963, 1970))
period(1963:1970)

period(range(catage.taf$Year))
period(catage.taf$Year)
period(catage.taf)
period(catage.xtab)
period(catage.long)

Description

Rename the last column in a data frame, by appending a "+" character. This is useful if the last column is a plus group.

Usage

plus(x)

Arguments

Value

A data frame similar to x, after renaming the last column.

Note

If the last column name already ends with a "+", the original data frame is returned without modifications.

See Also

names is the underlying function to rename columns.

TAF-package gives an overview of the package.

Examples

catage <- catage.taf

# Rename last column
catage <- plus(catage)

# Shorter and less error-prone than
names(catage)[names(catage)=="4"] <- "4+"

Description

Read metadata entries written in BibTeX format.

Usage

read.bib(file)

Arguments

Value

List of metadata entries.

Note

This function was created when the bibtex package was temporarily removed from CRAN. The current implementation reduces the TAF package dependencies to base R and nothing else.

This parser is similar to the read.bib function in the bibtex package, except:

• It returns a plain list instead of class bibentry.

• The fields bibtype and key are stored as list elements instead of attributes.

See the TAF Wiki page on bib entries.

See Also

taf.boot reads and processes metadata entries.

taf.sources reads metadata entries and adds a type field.

TAF-package gives an overview of the package.

Examples

## Not run: 
bib <- read.bib("DATA.bib")
str(bib)

## End(Not run)

Description

Read a TAF table from a file into a data frame.

Usage

read.taf(file, check.names = FALSE, stringsAsFactors = FALSE,
  fileEncoding = "UTF-8", ...)

Arguments

Details

Alternatively, file can be a directory or a vector of filenames, to read many tables in one call.

Value

A data frame in TAF format, or a list of data frames if file is a directory or a vector of filenames.

Note

This function gives a warning when column names are missing or duplicated. It also gives a warning if the data frame has zero rows.

See Also

read.csv is the underlying function used to read a table from a file.

write.taf writes a TAF table to a file.

TAF-package gives an overview of the package.

Examples

## Not run: 
write.taf(catage.taf, "catage.csv")
catage <- read.taf("catage.csv")

write.taf(catage)
file.remove("catage.csv")

## End(Not run)

Description

Remove empty directory under any operating system.

Usage

rmdir(path, recursive = FALSE)

Arguments

Value

TRUE for success, FALSE for failure, invisibly.

Note

The base function unlink(dir, recursive=FALSE) does not remove empty directories in Windows and unlink(dir, recursive=TRUE) removes non-empty directories, making it unsuitable for tidying up empty ones.

See Also

unlink with recursive = TRUE removes non-empty directories.

mkdir creates a new directory.

clean can be used to remove non-empty directories.

TAF-package gives an overview of the package.

Examples

## Not run: 
mkdir("emptydir")
rmdir("emptydir")

mkdir("outer/inner")
rmdir("outer", recursive=TRUE)

## End(Not run)

Description

Round column values in a data frame.

Usage

rnd(x, cols, digits = 0, grep = FALSE, ...)

Arguments

Value

A data frame similar to x, after rounding columns cols to the number of digits.

Note

Provides notation that is convenient for modifying many columns at once.

See Also

round is the underlying function used to round numbers.

grep is the underlying function used to match column names if grep is TRUE.

div is a similar function that divides columns with a common number.

TAF-package gives an overview of the package.

The icesAdvice package provides the icesRound function to round values for ICES advice sheets.

Examples

# With rnd() we no longer need to repeat the column names:

m <- mtcars
m[c("mpg","disp","qsec")] <- round(m[c("mpg","disp","qsec")])
m <- rnd(m, c("mpg","disp","qsec"))

# The x1/x2/x3/x4 approaches are equivalent:

x1 <- rnd(summary.taf, c("Rec","Rec_lo","Rec_hi",
                         "TSB","TSB_lo","TSB_hi",
                         "SSB","SSB_lo","SSB_hi",
                         "Removals","Removals_lo","Removals_hi"))
x1 <- rnd(x1, c("Fbar","Fbar_lo","Fbar_hi"), 3)

x2 <- rnd(summary.taf, "Rec|TSB|SSB|Removals", grep=TRUE)
x2 <- rnd(x2, "Fbar", 3, grep=TRUE)

x3 <- rnd(summary.taf, "Fbar", grep=TRUE, invert=TRUE)
x3 <- rnd(x3, "Fbar", 3, grep=TRUE)

# Less reliable in scripts if columns have been added/deleted/reordered:

x4 <- rnd(summary.taf, 2:13)
x4 <- rnd(x4, 14:16, 3)

Description

Convert a table from SAM format to TAF format.

Usage

sam2taf(x, colname = NULL, year = TRUE)

Arguments

Details

The default when colname = NULL is to try to infer a column name from the x argument. For example,

sam2taf(ssbtable(fit))
sam2taf(ssb)
sam2taf(SSB)

will recognize ⁠ssbtable⁠ calls and ⁠ssb⁠ object names, implicitly setting colname = "SSB" if the user does not pass an explicit value for colname.

Value

A data frame in TAF format.

Note

The stockassessment package provides accessor functions that return a matrix with columns ⁠Estimate⁠, ⁠Low⁠, and ⁠High⁠, while TAF tables are stored as data frames with a year column.

See Also

summary.taf describes the TAF format.

catchtable, fbartable, rectable, ssbtable, and tsbtable (in the stockassessment package) return matrices with SAM estimates and confidence limits.

The summary method for sam objects produces a summary table with some key quantities of interest, containing duplicated column names (⁠Low⁠, ⁠High⁠) and rounded values.

TAF-package gives an overview of the package.

Examples

# Example objects
x <- as.matrix(summary.taf[grep("SSB", names(summary.taf))])
rec <- as.matrix(summary.taf[grep("Rec", names(summary.taf))])
tsb <- as.matrix(summary.taf[grep("TSB", names(summary.taf))])
dimnames(x) <- list(summary.taf$Year, c("Estimate", "Low", "High"))
dimnames(rec) <- dimnames(tsb) <- dimnames(x)

# One SAM table, arbitrary object name
sam2taf(x)
sam2taf(x, "SSB")
sam2taf(x, "SSB", year=FALSE)

# Many SAM tables, recognized names
sam2taf(rec)
data.frame(sam2taf(rec), sam2taf(tsb, year=FALSE))

## Not run: 

# Accessing tables from SAM fit object
data.frame(sam2taf(rectable(fit)), sam2taf(tsbtable(fit), year=FALSE))

## End(Not run)

Description

Run core TAF scripts in current directory.

Usage

source.all(...)

Arguments

Value

Logical vector, indicating which scripts ran without errors.

Note

TAF scripts that will be run if they exist are: ⁠utilities.R⁠, ⁠data.R⁠, ⁠model.R⁠, ⁠output.R⁠, and ⁠report.R⁠.

The ⁠model.R⁠ script may also be named ⁠method.R⁠ and is treated in the same way.

See Also

source.taf runs a TAF script.

make.all runs all TAF scripts as needed.

clean cleans TAF directories.

TAF-package gives an overview of the package.

Examples

## Not run: 
source.all()

## End(Not run)

Description

Read all *.R files from a directory containing R functions.

Usage

source.dir(dir, pattern = "\\.[r|R]$", all.files = FALSE,
  recursive = FALSE, quiet = TRUE, ...)

Arguments

Details

The dir argument can also be a vector of filenames, instead of a directory name. This can be useful to specify certain files while avoiding others.

Value

Names of sourced files.

Note

This function is convenient in TAF analyses when many R utility functions are stored in a directory, see example below.

See Also

source is the base function to read R code from a file.

TAF-package gives an overview of the package.

Examples

## Not run: 
source.dir("boot/software/utilities")

## End(Not run)

Description

Run a TAF script and return to the original directory.

Usage

source.taf(script, rm = FALSE, clean = TRUE, detach = FALSE,
  taf = NULL, quiet = FALSE)

Arguments

Details

The default value of rm = FALSE is to protect users from accidental loss of work, but the TAF server always runs with rm = TRUE to make sure that only files, not objects in memory, are carried over between scripts.

Likewise, the TAF server runs with clean = TRUE to make sure that the script starts with a clean directory. The target directory of a TAF script has the same filename prefix as the script: ⁠data.R⁠ creates ‘data’ etc.

Value

TRUE or FALSE, indicating whether the script ran without errors.

Note

Commands within a script (such as setwd) may change the working directory, but source.taf guarantees that the working directory reported by getwd() is the same before and after running a script.

See Also

source is the base function to run R scripts.

make.taf runs a TAF script if needed.

source.all runs all TAF scripts in a directory.

TAF-package gives an overview of the package.

Examples

## Not run: 
write("print(pi)", "script.R")
source("script.R")
source.taf("script.R")
file.remove("script.R")

## End(Not run)

Description

Small summary results table to describe a TAF format data frame to store values by year.

Usage

summary.taf

Format

Data frame containing 16 columns:

Details

The data are an excerpt (first years) from the summary results table for North Sea cod from the ICES (2016) assessment.

Source

ICES (2016). Report of the working group on the assessment of demersal stocks in the North Sea and Skagerrak (WGNSSK). ICES CM 2016/ACOM:14, p. 673. doi:10.17895/ices.pub.5329.

See Also

div and rnd can modify a large number of columns.

TAF-package gives an overview of the package.

Examples

summary.taf
x <- div(summary.taf, "Rec|TSB|SSB|Removals", grep=TRUE)
x <- rnd(x, "Rec|TSB|SSB|Removals", grep=TRUE)
x <- rnd(x, "Fbar", 3, grep=TRUE)

Description

Process metadata files ‘SOFTWARE.bib’ and ‘DATA.bib’ to set up software and data files required for the analysis.

Usage

taf.boot(software = TRUE, data = TRUE, clean = TRUE, force = FALSE,
  taf = NULL, quiet = FALSE, ...)

Arguments

Details

If clean = TRUE then:

1. clean.software and clean.library are run if ‘SOFTWARE.bib’ is processed.

2. clean.data is run if ‘DATA.bib’ is processed.

The default behavior of taf.boot is to skip downloading of remote files (GitHub resources, URLs, boot scripts) and also skip installing R packages from GitHub if the files seem to be already in place. This is done to speed up the boot procedure as much as possible. To override this and guarantee that all data and software files are updated, pass force = TRUE to download and install everything declared in ⁠SOFTWARE.bib⁠ and ⁠DATA.bib⁠.

Value

Logical vector indicating which metadata files were processed.

Note

This function should be called from the top directory of a TAF analysis. It looks for a directory called ‘boot’ and prepares data files and software according to metadata specifications.

The boot procedure consists of the following steps:

1. If a ⁠boot/SOFTWARE.bib⁠ metadata file exists, it is processed.

2. If a ⁠boot/DATA.bib⁠ metadata file exists, it is processed.

After the boot procedure, software and data have been documented and are ready to be used in the subsequent analysis. Specifically, the procedure populates up to three new directories:

• ⁠boot/data⁠ with data files.

• ⁠boot/library⁠ with R packages compiled for the local platform.

• ⁠boot/software⁠ with software files, such as R packages in ⁠tar.gz⁠ source code format.

From version 4.2 onwards, the term boot is preferred for what used to be called bootstrap, mainly to avoid confusion with statistical bootstrap. To taf.boot() is similar to booting a computer, readying the components required for subsequent computations. Help pages now refer to boot, but all TAF functions fully support existing analyses that have a legacy bootstrap folder.

Model settings and configuration files can be set up within ⁠DATA.bib⁠, see TAF Wiki.

See Also

draft.data and draft.software can be used to create initial draft versions of ‘DATA.bib’ and ‘SOFTWARE.bib’ metadata files.

taf.library loads a package from ⁠boot/library⁠.

TAF-package gives an overview of the package.

Examples

## Not run: 
taf.boot()

## End(Not run)

Description

Construct a relative path to the boot folder, regardless of whether the current working directory is the TAF root, the boot folder, or a subfolder inside boot.

Usage

taf.boot.path(..., fsep = .Platform$file.sep)

Arguments

Value

Relative path, or a vector of paths.

Note

This function is especially useful in boot scripts.

See Also

file.path is the underlying function used to construct the path.

taf.data.path constructs the path to boot data files.

TAF-package gives an overview of the package.

Examples

## Not run: 
taf.boot.path()
taf.boot.path("software")

## End(Not run)

Description

Predefined colors that can be useful in TAF plots.

Usage

taf.green
taf.orange
taf.blue
taf.dark
taf.light

See Also

TAF-package gives an overview of the package.

Examples

taf.green

opar <- par(mfrow=c(3,1))
barplot(5:1, main="Five",
        col=c(taf.green, taf.orange, taf.blue, taf.dark, taf.light))

barplot(6:1, main="Six", col=c(taf.green, taf.orange, taf.blue,
                               taf.dark, taf.light, "white"))

barplot(7:1, main="Seven", col=c("black", taf.dark, taf.light,
                                 taf.green, taf.orange, taf.blue, "white"))
par(opar)

Description

Construct a relative path to data files in the boot data folder, regardless of whether the current working directory is the TAF root, the boot folder, or a subfolder inside boot.

Usage

taf.data.path(..., fsep = .Platform$file.sep)

Arguments

Value

Relative path, or a vector of paths.

Note

This function is especially useful in boot scripts.

See Also

file.path is the underlying function used to construct the path.

taf.boot.path constructs the path to the boot folder.

TAF-package gives an overview of the package.

Examples

taf.data.path()
taf.data.path("example.dat")

Description

Install packages in ‘tar.gz’ format in local TAF library.

Usage

taf.install(targz = NULL, lib = taf.boot.path("library"), quiet = FALSE)

Arguments

Details

If ⁠targz = NULL⁠, all packages found in ⁠boot/software⁠ are installed, as long as they have filenames of the form ⁠package_sha.tar.gz⁠ containing a 7-character SHA reference code.

The default behavior of taf.install is to install packages in alphabetical order. When the installation order matters because of dependencies, the user can specify a vector of package filenames to install.

Value

No return value, called for side effects.

Note

The taf.boot procedure downloads and installs R packages, without requiring the user to run taf.install. The main reason for a TAF user to run taf.install directly is to initialize and run a TAF analysis without running the boot procedure, e.g. to avoid updating the underlying datasets and software.

After installing the package, this function writes the remote SHA reference code into the package files ⁠DESCRIPTION⁠ and ⁠Meta/package.rds⁠.

See Also

taf.boot calls download.github and taf.install to download and install R packages.

taf.library loads a package from ⁠boot/library⁠.

clean.library selectively removes packages from the local TAF library.

install.packages is the underlying base function to install a package.

TAF-package gives an overview of the package.

Examples

## Not run: 
# Install one package
taf.install("boot/software/FLAssess_f1e5acb.tar.gz")

# Install all packages found in boot/software
taf.install()

## End(Not run)

Description

Add TAF library to the search path for R packages.

Usage

taf.libPaths(remove = FALSE)

Arguments

Value

The resulting vector of file paths.

Warning

An unwanted side effect of having the TAF library as the first element in the search path is that install.packages will then install packages inside ⁠boot/library⁠. This is not a serious side effect, since a subsequent call to taf.boot or clean.library will remove packages from the TAF library that are not declared in the ‘SOFTWARE.bib’ file.

Note

Specifically, this function sets "boot/library" as the first element of .libPaths(). This is rarely beneficial in TAF scripts, but can be useful when using the sessioninfo package, for example.

See Also

.libPaths is the underlying function to modify the search path for R packages.

taf.library loads a package from ⁠boot/library⁠.

TAF-package gives an overview of the package.

Examples

taf.libPaths()
taf.libPaths(remove=TRUE)

Description

Load and attach all packages from local TAF library.

Usage

taf.libraries(messages = FALSE, warnings = FALSE)

Arguments

Value

TRUE (invisibly) if all packages loaded.

Note

Packages in the TAF library are loaded in the order in which they are listed in ⁠SOFTWARE.bib⁠. Internal dependencies can in this way be respected.

See Also

taf.library is the TAF function called for each found package.

TAF-package gives an overview of the package.

Examples

## Not run: 
# Load all packages in TAF library
taf.libraries()

## End(Not run)

Description

Load and attach package from local TAF library.

Usage

taf.library(package, messages = FALSE, warnings = FALSE)

Arguments

Value

The names of packages currently installed in the TAF library.

Note

The purpose of the TAF library is to retain R packages that are not commonly used (and not on CRAN), to support long-term reproducibility of TAF analyses.

If a package has dependencies that are also in the TAF library, they will be loaded in preference of any version that may be installed in the system or user library. To force the use of a dependency from outside of the TAF library call ⁠library(package)⁠ prior to the call to ⁠taf.library⁠.

See Also

library is the underlying base function to load and attach a package.

taf.boot is the procedure to install packages into a local TAF library, via the ⁠SOFTWARE.bib⁠ metadata file.

detach.packages detaches all packages.

TAF-package gives an overview of the package.

Examples

## Not run: 

# Show packages in TAF library
taf.library()

# Load packages
taf.library(this)
taf.library(that)

## End(Not run)

Description

Open PNG graphics device to export a plot into the TAF ⁠report⁠ folder.

Usage

taf.png(filename, width = 1600, height = 1200, res = 200, ...)

Arguments

Details

The filename can be passed without the preceding "report/", and without the ".png" filename extension.

Specifically, the function prepends "report/" to the filename if (1) the filename does not contain a "/" separator, (2) the working directory is not ⁠report⁠, and (3) the directory ⁠report⁠ exists. The function also appends ⁠".png"⁠ to the filename if it does not already have that filename extension.

This automatic filename manipulation can be bypassed by using the png function directly.

Value

No return value, called for side effects.

Note

A simple convenience function to shorten

png("report/plot.png", width=1600, height=1200, res=200)

to

taf.png("plot")

The res argument affects the text size, along with all other plot elements. To change the text size of specific lattice plot elements, the zoom function can be helpful.

For consistent image width and text size, it can be useful to keep the default width = 1600 but vary the height to adjust the desired aspect ratio for each plot.

See Also

png is the underlying function used to open a PNG graphics device.

zoom changes text size in a lattice plot.

TAF-package gives an overview of the package.

Examples

## Not run: 
taf.png("myplot")
plot(1)
dev.off()

library(lattice)
taf.png("mytrellis")
xyplot(1~1)
dev.off()

library(ggplot2)
taf.png("myggplot")
qplot(1, 1)
dev.off()

## End(Not run)

Description

Show session information about loaded packages, clearly indicating which packages were loaded from the local TAF library.

Usage

taf.session(sort = FALSE, imports = TRUE, details = FALSE)

Arguments

Value

List containing session information about loaded packages.

See Also

sessionInfo and the sessioninfo package provide similar information, but do not indicate clearly packages that were loaded from the local TAF library.

TAF-package gives an overview of the package.

Examples

taf.session()
taf.session(sort=TRUE)
taf.session(imports=FALSE)
taf.session(details=TRUE)

Description

Create initial directories and R scripts for a new TAF analysis.

Usage

taf.skeleton(path = ".", force = FALSE, pkgs = "TAF",
  model.script = "model.R", gitignore = TRUE)

Arguments

Details

When gitignore = TRUE, the following entries will be written to a ⁠.gitignore⁠ file, appending if the file exists already:

/boot/data
/boot/library
/boot/software
/data
/model
/output
/report
*.Rproj
.RData
.Rhistory
.Rproj.user
.Ruserdata

Value

Full path to analysis directory.

See Also

package.skeleton creates an empty template for a new R package.

TAF-package gives an overview of the package.

Examples

## Not run: 
taf.skeleton()

## End(Not run)

Description

List metadata entries from DATA.bib, SOFTWARE.bib, or both.

Usage

taf.sources(type)

Arguments

Value

List of metadata entries.

Note

The functionality is similar to read.bib, with the addition of a type field, indicating whether an entry is data software.

This function is used internally by the taf.boot procedure and is also useful when organizing a larger TAF project.

See Also

taf.boot reads and processes metadata entries.

read.bib is the underlying function to read metadata entries.

process.entry processes a single metadata entry, in the list format returned by taf.sources.

Examples

## Not run: 
taf.sources("data")
taf.sources("software")
taf.sources("both")

## End(Not run)

Description

Extract files from a zip archive, retaining executable file permissions.

Usage

taf.unzip(zipfile, files = NULL, exdir = ".", unzip = NULL, ...)

Arguments

Details

The default method unzip = NULL uses the external unzip program in Unix-compatible operating systems, but an internal method in Windows. For additional information, see the unzip help page.

Value

No return value, called for side effects.

Note

One shortcoming of the base unzip function is that the default "internal" method resets file permissions, so Linux and macOS executables will return a ⁠'Permission denied'⁠ error when run.

This function is identical to the base unzip function, except the default value unzip = NULL chooses an appropriate extraction method in all operating systems, making it useful when writing platform-independent scripts.

See Also

unzip is the base function to unzip files.

TAF-package gives an overview of the package.

Examples

## Not run: 
exefile <- if(os.unix()) "run" else "run.exe"
taf.unzip("boot/software/archive.zip", files=exefile, exdir="model")

## End(Not run)

Description

Convert a TAF table to HTML code and optionally write to a file.

Usage

taf2html(x, file = "", align = "", header = align,
  digits = getOption("digits"), center = "style=\"text-align:center\"",
  left = "style=\"text-align:left\"",
  right = "style=\"text-align:right\"", append = FALSE)

Arguments

Details

The align argument can be a vector of strings to specify column-specific alignment, for example c("l","r","l","l"). Only the first letter (case-insensitive) is used, so "left" is equivalent to "L". An empty string (the default), or any string that does not begin with C, L, or R indicates no specific alignment.

The header argument can be used to specify an alignment for the column names that is different from the data values. The default is to use the same alignment as the data values.

The center, left, and right arguments can be used to specify the exact HTML attribute to render alignment, for users who are familiar with cascading style sheets (CSS). For example, the long-winded style="text-align:center" could be shortened to class="L" if a corresponding class has been defined in CSS.

Instead of using file to pass a filename, it can have the special value file = NULL to return the HTML code as a vector of strings or file = "" (the default) to show the HTML in the console.

Value

NULL, or a vector of strings if file = NULL.

Note

The resulting HTML conforms to the HTML5 standard and aims for compact output, omitting optional closing tags and rendering each row of data as one row of HTML code.

See Also

write.taf writes a TAF table to a file.

TAF-package gives an overview of the package.

Examples

Description

Convert a table from TAF format to long format.

Usage

taf2long(x, names = c("Year", "Age", "Value"))

Arguments

Value

A data frame with three columns.

Note

TAF stores tables as data frames, usually with a year column as seen in stock assessment reports. The long format is more convenient for analysis and producing plots.

See Also

catage.taf and catage.long describe the TAF and long formats.

long2taf converts a long table to TAF format.

TAF-package gives an overview of the package.

Examples

taf2long(catage.taf, names=c("Year","Age","Catch"))

Description

Convert a table from TAF format to crosstab format.

Usage

taf2xtab(x)

Arguments

Value

A data frame with years as row names.

Note

TAF stores tables as data frames, usually with a year column as seen in stock assessment reports. The crosstab format can be more convenient for analysis and producing plots.

See Also

catage.taf and catage.xtab describe the TAF and crosstab formats.

tt converts a TAF table to transposed crosstab format.

xtab2taf converts a crosstab table to TAF format.

TAF-package gives an overview of the package.

Examples

taf2xtab(catage.taf)

Description

Convert a table from TAF format to transposed crosstab format.

Usage

tt(x, column = FALSE)

Arguments

Value

A data frame with years as column names.

Note

Transposing can be useful when comparing TAF tables to stock assessment reports.

See Also

t transposes a matrix.

catage.taf describes the TAF format.

taf2xtab converts a TAF table to crosstab format, without transposing.

TAF-package gives an overview of the package.

Examples

taf2xtab(catage.taf)
tt(catage.taf)
tt(catage.taf, TRUE)
tt(catage.taf, "Custom")

Description

Write a TAF table to a file.

Usage

write.taf(x, file = NULL, dir = NULL, quote = FALSE, row.names = FALSE,
  fileEncoding = "UTF-8", underscore = TRUE, ...)

Arguments

Details

Alternatively, x can be a list of data frames or a string vector of object names, to write many tables in one call. The resulting files are named automatically, similar to file = NULL.

The default value file = NULL uses the name of x as a filename, so a data frame called survey.uk will be written to a file called ‘survey_uk.csv’ (when underscore = TRUE) or ‘survey.uk.csv’ (when underscore = FALSE).

The special value file = "" prints the data frame in the console, similar to write.csv.

Value

No return value, called for side effects.

Note

This function gives a warning when column names are missing or duplicated, unless the target directory name is ⁠report⁠. It also gives a warning if the data frame has zero rows.

See Also

write.csv is the underlying function used to write a table to a file.

read.taf reads a TAF table from a file into a data frame.

taf2html converts TAF table to HTML.

TAF-package gives an overview of the package.

Examples

## Not run: 
write.taf(catage.taf, "catage.csv")
catage <- read.taf("catage.csv")

write.taf(catage)
file.remove("catage.csv")

## End(Not run)

Description

Convert a table from crosstab format to long format.

Usage

xtab2long(x, names = c("Year", "Age", "Value"))

Arguments

Value

A data frame with three columns.

See Also

catage.xtab and catage.long describe the crosstab and long formats.

xtab2taf and taf2long are the underlying functions that perform the conversion.

TAF-package gives an overview of the package.

Examples

xtab2long(catage.xtab, names=c("Year","Age","Catch"))

Description

Convert a table from crosstab format to TAF format.

Usage

xtab2taf(x, colname = "Year")

Arguments

Value

A data frame in TAF format.

Note

TAF stores tables as data frames, usually with a year column as seen in stock assessment reports. The crosstab format can be more convenient for analysis and producing plots.

See Also

catage.xtab and catage.taf describe the crosstab and TAF formats.

taf2xtab converts a TAF table to crosstab format.

TAF-package gives an overview of the package.

Examples

xtab2taf(catage.xtab)

Description

Change text size in a lattice plot.

Usage

zoom(x, ...)

## S3 method for class 'trellis'
zoom(x, size = 1, main = 1.2 * size, lab = size,
  axis = size, strip = size, sub = 0.9 * size, legend = 0.9 * size,
  splom = 0.9 * size, ...)

Arguments

Details

Pass NULL for any argument to avoid changing the size of that text component.

The legend component of a lattice plot can be somewhat fickle, as the object structure varies between plots. One solution is to pass legend = NULL and tweak the legend before or after calling the zoom function.

Value

The same lattice object, but with altered text size.

Note

The default values result in lattice plots that have similar text size as base plots, when using taf.png.

This function ends with a print call, to make it easy to export the lattice plot to a file, without the need of an explicit print.

See Also

Lattice plots are created using xyplot or related functions.

taf.png opens a PNG graphics device.

TAF-package gives an overview of the package.

Examples

library(lattice)

xyplot(1~1)
zoom(xyplot(1~1))
zoom(xyplot(1~1), size=1.2)
zoom(xyplot(1~1), axis=0.8)
zoom(xyplot(1~1), axis=NULL)

## Not run: 
taf.png("myplot")
plot(1)
dev.off()

taf.png("mytrellis")
xyplot(1~1)
dev.off()

taf.png("mytrellis_zoom")
