In r-lib/crancache: Transparent Caching of Packages from CRAN-Like Repositories

Install Packages from Repositories or Local Files, with Caching

Description

Install Packages from Repositories or Local Files, with Caching

Usage

install_packages(pkgs, lib, repos = getOption("repos"),
  contriburl = contrib.url(repos, type), method, available = NULL,
  destdir = NULL, dependencies = NA, type = getOption("pkgType"),
  ...)

Arguments

pkgs	character vector of the names of packages whose current versions should be downloaded from the repositories. If repos = NULL, a character vector of file paths. These can be source directories or archives or binary package archive files (as created by R CMD build --binary). (http:// and file:// URLs are also accepted and the files will be downloaded and installed from local copies.) On a CRAN build of R for macOS these can be ‘.tgz’ files containing binary package archives. Tilde-expansion will be done on file paths. If this is missing or a zero-length character vector, a listbox of available packages is presented where possible in an interactive R session.
lib	character vector giving the library directories where to install the packages. Recycled as needed. If missing, defaults to the first element of .libPaths().
repos	character vector, the base URL(s) of the repositories to use, e.g., the URL of a CRAN mirror such as "https://cloud.r-project.org". For more details on supported URL schemes see url. Can be NULL to install from local files, directories or URLs: this will be inferred by extension from pkgs if of length one.
contriburl	URL(s) of the contrib sections of the repositories. Use this argument if your repository mirror is incomplete, e.g., because you burned only the ‘contrib’ section on a CD, or only have binary packages. Overrides argument repos. Incompatible with type = "both".
method	download method, see download.file. Unused if a non-NULL available is supplied.
available	a matrix as returned by available.packages listing packages available at the repositories, or NULL when the function makes an internal call to available.packages. Incompatible with type = "both".
destdir	directory where downloaded packages are stored. If it is NULL (the default) a subdirectory downloaded_packages of the session temporary directory will be used (and the files will be deleted at the end of the session).
dependencies	logical indicating whether to also install uninstalled packages which these packages depend on/link to/import/suggest (and so on recursively). Not used if repos = NULL. Can also be a character vector, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances"). Only supported if lib is of length one (or missing), so it is unambiguous where to install the dependent packages. If this is not the case it is ignored, with a warning. The default, NA, means c("Depends", "Imports", "LinkingTo"). TRUE means to use c("Depends", "Imports", "LinkingTo", "Suggests") for pkgs and c("Depends", "Imports", "LinkingTo") for added dependencies: this installs all the packages needed to run pkgs, their examples, tests and vignettes (if the package author specified them correctly). In all of these, "LinkingTo" is omitted for binary packages.
type	character, indicating the type of package to download and install. Will be "source" except on Windows and some macOS builds: see the section on ‘Binary packages’ for those.
...	additional arguments are passed to utils::install.packages().
