Arguments

Details

In combination with the lazyRepo function, this manifest can be used to work from a local, working checkout of a set of inter-dependent Bioconductor packages.

Value

A PkgManifest which contains SVN locations for all packages found in the specified bioc repositories, as well as those listed in not_in_repo

See Also

lazyRepo

Description

A constructor for creating a RepoSubset object for a specified release of Bioconductor, which includes only the BiocInstaller package.

Arguments

Description

Create a Pkg manifest which points to tarballs representing a particular version of a CRAN package and versions of its (recursive) dependencies that were contemporary on the first or last day the specified package version resided on CRAN

Usage

cranPkgVersManifest(
  pkg,
  vers,
  earliest = TRUE,
  cur_avail = available.packages(),
  verbose = FALSE,
  suggests = c("direct", "none"),
  delay = 1,
  erronfail = TRUE
)

Arguments

Value

A SessionManifest object

Note

Some packages retain the same version on CRAN for long periods of time. The cohort in the manifest represents a gross proxy for the cohort used in conjunction within an analysis which used a the vers version of the specified package. In general it will *not* perfectly recreate the set of package versions originally used.

Arguments

Value

A path to the downloaded tarball, or NULL

Description

Unload currently loaded packages from the current R session

Usage

flushSession(dontunload = switchrDontUnload())

Arguments

Details

Attached packages are detached (and unloaded) first. After this is done, loaded packages, such as those imported by (previously) attached packages, are unloaded.

Finally, after all packages have been unloaded, native libraries loaded by those packages are unloaded (on systems where this is supported).

Value

NULL, called for its side-effect of unloading packages

Note

Failing to include switchr, any of its dependencies, or any base packages (available as a vector in the switchDeps object) in dontunload will result in undefined, likely erroneous behavior.

Description

full_libpaths(seed)

Arguments

Description

Usage

GithubManifest(..., pkgrepos)

Arguments

Details

Any names of the pkgrepos vector are assumed to be pkg names for the manifest. For unnamed elements, the pkg name is assumed to be the repository name.

Note

This is a convenience wrapper for makeManifest. It uses the username/repo[/subdir][@ref] shorthand for specifying package locations in github repositories introduced by Wickham's devtools. Unlike devtools, username is not optional, and only branch names are currently supported in the @ref

Examples

ghman = GithubManifest("gmbecker/switchr", "hadley/devtools")
ghman

Description

This is a low-level function not intended for direct use by the end user.

Usage

tail(x, ...)

## S4 method for signature 'SessionManifest'
tail(x, n = 5, ...)

## S4 method for signature 'PkgManifest'
tail(x, n = 5, ...)

Arguments

Details

In the case of a PkgManifest, the first or last n packages are retained in the manifest, while all others are removed.

In the case of a SessionManifest, n specified versions are retained, while the underlying PkgManifest is unchanged.

Value

An object of the same type as x containing n packages

Description

Install packages from a set of traditional repositories, or a Just-in-time repository constructed using a PkgManifest or SessionManifest

Usage

install_packages(pkgs, repos, versions = NULL, verbose = FALSE, ...)

## S4 method for signature 'character,character'
install_packages(pkgs, repos, versions = NULL, verbose = FALSE, ...)

## S4 method for signature 'character,missing'
install_packages(pkgs, repos, versions = NULL, verbose = FALSE, ...)

## S4 method for signature 'SessionManifest,ANY'
install_packages(pkgs, repos, versions = NULL, verbose = FALSE, ...)

## S4 method for signature 'character,SessionManifest'
install_packages(pkgs, repos, versions = NULL, verbose = FALSE, ...)

## S4 method for signature 'character,PkgManifest'
install_packages(pkgs, repos, versions = NULL, verbose = FALSE, ...)

Arguments

Details

In addition to installing the specified packages, this function annotates the installed DESCRIPTION files with provenance information about where the packages were installed from. This retains the information necessary to generate a manifest of installed packages for publication or reinstallation.

When repos is a vector of traditional repositories, this function - with the exception of the provenance mentioned above - behaves identically to install.packages. Otherwise, a Just-in-Time package repository is constructed using the information in the manifest(s) passed to repos, which is then used in conjuction with link{install.packages} to do the actual installation.

## End(Not run)

Description

Create a lazy repository for installing directly from a package manifest. Most users will want to call Install directly, which will call this as needed behind the scenes.

Usage

lazyRepo(
  pkgs,
  pkg_manifest,
  versions = rep(NA, times = length(pkgs)),
  dir = tempdir(),
  rep_path = file.path(dir, "repo"),
  get_suggests = FALSE,
  verbose = FALSE,
  scm_auths = list(bioconductor = c("readonly", "readonly")),
  param = SwitchrParam(),
  force_refresh = FALSE
)

## S4 method for signature 'SessionManifest,ANY'
lazyRepo(
  pkgs,

  get_suggests = FALSE,
  verbose = FALSE,
  scm_auths = list(bioconductor = c("readonly", "readonly")),
  param = SwitchrParam(),
  force_refresh = FALSE
)

## S4 method for signature 'PkgManifest,ANY'
lazyRepo(
  pkgs,
  pkg_manifest,
  versions = rep(NA, times = length(pkgs)),
  dir = tempdir(),
  rep_path = file.path(dir, "repo"),
  get_suggests = FALSE,
  verbose = FALSE,
  scm_auths = list(bioconductor = c("readonly", "readonly")),
  param = SwitchrParam(),
  force_refresh = FALSE
)

## S4 method for signature 'character,SessionManifest'
lazyRepo(
  pkgs,
  pkg_manifest,
  versions = rep(NA, times = length(pkgs)),
  dir = tempdir(),
  rep_path = file.path(dir, "repo"),
  get_suggests = FALSE,
  verbose = FALSE,
  scm_auths = list(bioconductor = c("readonly", "readonly")),
  param = SwitchrParam(),
  force_refresh = FALSE
)

## S4 method for signature 'character,PkgManifest'
lazyRepo(
  pkgs,
  pkg_manifest,
  versions = rep(NA, times = length(pkgs)),
  dir = tempdir(),
  rep_path = file.path(dir, "repo"),
  get_suggests = FALSE,
  verbose = FALSE,
  scm_auths = list(bioconductor = c("readonly", "readonly")),
  param = SwitchrParam(),
  force_refresh = FALSE
)

Arguments

Details

When checking building from SVN or git checkouts, this function will first look for existing checkouts for the relevant packages in dir. If found, these will be updated (in the case of conflicts, the behavior is undefined and will likely fail if they are not resolvable). This allows the user to have an existing, checkout directory where he or she works on development versions of multiple, interrelated packages, as local changes WILL be reflected in the packages built into the lazy repository.

Value

A path to the populated lazy repository, suitable for 'coercing' to a url and installing from.

  lib = currentCompEnv(),
  record_versions = TRUE,
  known_manifest = makeManifest(dep_repos = repos),
  repos = defaultRepos(),
  ...
)

## S4 method for signature 'missing'

  ...
)

## S4 method for signature 'character'
libManifest(
  lib = currentCompEnv(),
  record_versions = TRUE,
  known_manifest = makeManifest(dep_repos = repos),

)

## S4 method for signature 'SwitchrCtx'
libManifest(
  lib = currentCompEnv(),
  record_versions = TRUE,
  known_manifest = makeManifest(dep_repos = repos),
  repos = defaultRepos(),
  ...
)

Arguments

Note

The manifest generated by this function will not include base packages, as they are part of R and not installable in the traditional sense.

Examples

man = libManifest()
man

## Not run: 
man2 = libManifest("myotherlib")
man2

## End(Not run)

Description

)

Arguments

Value

The full path to the downloaded file , or NULL if unable to locate the package

Note

Locating and attempting to install a non-current version of a single will not work in general, due to dependency issues. In most cases a Just-in-Time repository should be created and used instead, e.g. via install_packages

This function is called internally during the construction of Just-in-Time repositories and during the installation of specific package versions.

Description

Get or set packages which should NOT be unloaded when flushing the system, e.g., when switching between libraries.

Usage

switchrDontUnload(value, add = TRUE)

Arguments

Note

By default switchr will not attempt to unload any base packages, itself, or any of its dependencies. Attempting to unload any of these packages (e.g. add=FALSE) will result in undefined behavior and is not recommended.

Description

Generate a manifest of all currently available (existing) swtichr libraries.

Usage

switchrManifest()

Value

A data.frame with information about the located switchr libraries

Note

This function reads cached metadata from the current switchr base directory (~/.switchr by default). This cache is updated whenever the switchr framework is used to create or destroy a switchr library, but will not be updated if one is added or removed manually. In such cases updateManifest must be called first

Description

Set whether or not ANY packages are unloaded when switching libraries.

Usage

switchrNoUnload(value)

Arguments

Details

This should be set to TRUE when using switchr in the context of dynamic documents such as .Rnw and .Rmd files.

Value

A logical indicating whether or not calling flushSession will skipped during the library switching process.

Description

A contstructor for a SwitchrParam object representing a number of common parameters understood by the switchr framework

Usage

SwitchrParam(
  logfun = function(...) NULL,
  shell_init = character(),
  archive_timing = 2,
  archive_retries = 2,
  dl_method,
  shell_timing = 1
)

Arguments

Value

A SwitchrParam object.

  exclude.site = TRUE,
  ...
)

## S4 method for signature 'character,character'

  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

## S4 method for signature 'character,SwitchrCtx'
switchTo(
  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

## S4 method for signature 'character,missing'
switchTo(
  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

## S4 method for signature 'SwitchrCtx,ANY'
switchTo(
  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

## S4 method for signature 'character,RepoSubset'
switchTo(
  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

## S4 method for signature 'character,PkgManifest'
switchTo(
  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

## S4 method for signature 'character,SessionManifest'
switchTo(
  name,
  seed = NULL,
  reverting = FALSE,
  ignoreRVersion = FALSE,
  exclude.site = TRUE,
  ...
)

Arguments

Details

If switchr does not now about the specified computing environment, a new one will be created via installCompEnv. This includes creating a directory under the switchr base directory and installing packages into it. See installCompEnv for more details.

This function has the side effect of unloading all loaded packages (other than base packages, GRAN or GRANBAse, switchr itself, and switchr's dependencies) and the associated DLLs. It also changes the library location R will use to search for packages, e.g. when you call library.

This means you will have to reinstall packages after switching, which is important and intended (e.g. when switching to using Bioc devel from Bioc release).

Value

Invisibly returns the SwitchrCtx object representing the new computing environment

Note

By default, this process involves a call to flushSession which will attempt to unload all loaded packages. While some support of configuring what is unloaded is provided via switchrDontUnload, it is recommended that you turn this feature entirely off via switchrNoUnload(TRUE) when using switchr within dyanmic documents (.Rnw/.Rmd files, etc), particularly when using the knitr package.

Value

Depends, see system for details.

Description

Update an existing repository by reading the PACKAGES file and only processing built package tarballs which do not match existing entries.

update_PACKAGES can be much faster than write_PACKAGES for small-moderate changes to large repository indexes.

Usage

update_PACKAGES(
  dir = ".",
  fields = NULL,
  type = c("source", "mac.binary", "win.binary"),
  verbose = dryrun,
  unpacked = FALSE,
  subdirs = FALSE,
  latestOnly = TRUE,
  addFiles = FALSE,
  strict = TRUE,
  dryrun = FALSE,
  logfun = message,
  ...
)

Arguments

Details

Throughout this section, package tarball is taken to mean a tarball file in dir whose name can be interpreted as <package>_<version>.<ext> (or that is pointed to by the File field of an existing PACKAGES entry). Novel package tarballs are those which do not match an existing PACKAGES file entry.

update_PACKAGES avoids (re)processing package tarballs in cases where a PACKAGES file entry already exists and appears to remain valid. The logic for detecting still-valid entries is as follows:

Currently update_PACKAGES calls directly down to write_PACKAGES (and thus no speedup should be expected) if any of the following conditions hold:

• No PACKAGES file exists under dir

• unpacked is TRUE

• subdirs is anything other than FALSE

• fields is not NULL and one or more specified fields are not present in the existing PACKAGES file

All package tarballs whose last modify times are later than that of the existing PACKAGES file are considered novel and no attempt is made to identify or retain any corresponding PACKAGES entries. Similarly, all PACKAGES entries which have no corresponding package tarball are definitionally invalid.

When strict = TRUE, PACKAGES entries which appear to match a package tarball are confirmed via MD5 checksum; those that pass are retained as valid. All novel package tarballs are fully proccessed by the standard write_PACKAGES machinery, and the resulting entries are added. Finally, if latestOnly = TRUE, package-version pruning is performed across the entries.

When strict = FALSE, package tarballs are assumed to encode correct metadata in their filenames. PACKAGES entries which appear to match a package tarball are retained as valid (No MD5sum checking occurs). If latestOnly = TRUE, package-version pruning across the full set of retained entries and novel package tarballs before the processing of the novel tarballs, at significant computational and time savings in some situations. After the optional pruning, any relevant novel package tarballs are processed via write_PACKAGES and added to the set of retained entries.

After the above process concludes, the final database of PACKAGES entries is written to all three PACKAGES files, overwriting the existing files.

Note

While both strict and nonstrict modes offer speedups when updating small percentages of large repositories, non-strict mode is much faster and is recommended in situations where the assumptions it makes are safe.
