addOldPackage: Add old package versions to a miniCRAN repository.

In miniCRAN: Create a Mini Version of CRAN Containing Only Selected Packages

Add old package versions to a miniCRAN repository.

Description

Will download and add older source package versions. Older binary versions are not normally available on CRAN and should be built from source on the platform for which they are required. As such, specifying type!="source" will likely fail as the download will not be successful.

Usage

addOldPackage(
  pkgs = NULL,
  path = NULL,
  vers = NULL,
  repos = getOption("repos"),
  type = "source",
  Rversion = R.version,
  writePACKAGES = TRUE,
  deps = FALSE,
  quiet = TRUE
)

Arguments

pkgs	Character vector of packages to download
path	Destination download path. This path is the root folder of your new repository.
vers	The package version to install.
repos	URL(s) of the 'contrib' sections of the repositories, e.g. "https://cran.us.r-project.org". Passed to available.packages()
type	Possible values are (currently) "source", "mac.binary" and "win.binary": the binary types can be listed and downloaded but not installed on other platforms. Passed to download.packages().
Rversion	Version of R (only used if type is not source.) Defaults to R.version, but this can be specified as any of the following formats: a character string with the two digit R version, e.g. "3.1" a list with components major and minor the result of getRversion() the result of R.version
writePACKAGES	If TRUE, calls write_PACKAGES() to update the repository PACKAGES file.
deps	logical indicating whether the package dependencies should be added (default TRUE).
quiet	If TRUE, suppress status messages (if any), and the progress bar during download.

Value

Adds the packages, rebuilds the package index, and invisibly returns the number of packages written to the index files.

Note

Dependencies for old package versions cannot be determined automatically and must be specified by the user in pkgs and vers. Thus, deps=FALSE is the default for this function.
