update_packages: Update Outdated Packages, with Caching

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

Update Outdated Packages, with Caching

Description

Update Outdated Packages, with Caching

Usage

update_packages(lib.loc = NULL, repos = getOption("repos"),
  contriburl = contrib.url(repos, type), method, instlib = NULL,
  ask = TRUE, available = NULL, oldPkgs = NULL, ...,
  checkBuilt = FALSE, type = getOption("pkgType"))

Arguments

lib.loc	character vector describing the location of R library trees to search through (and update packages therein), or NULL for all known trees (see .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".
contriburl	URL(s) of the contrib sections of the repositories. Use this argument if your repository is incomplete. Overrides argument repos. Incompatible with type = "both".
method	Download method, see download.file. Unused if a non-NULL available is supplied.
instlib	character string giving the library directory where to install the packages.
ask	logical indicating whether to ask the user to select packages before they are downloaded and installed, or the character string "graphics", which brings up a widget to allow the user to (de-)select from the list of packages which could be updated. (The latter value only works on systems with a GUI version of select.list, and is otherwise equivalent to ask = TRUE.)
available	an object as returned by available.packages listing packages available at the repositories, or NULL which makes an internal call to available.packages. Incompatible with type = "both".
oldPkgs	if specified as non-NULL, update_packages() only considers these packages for updating. This may be a character vector of package names or a matrix as returned by old.packages.
...	additional arguments are passed to utils::update.packages().
checkBuilt	If TRUE, a package built under an earlier major.minor version of R (e.g., 3.4) is considered to be ‘old’.
type	character, indicating the type of package to download and install. See install.packages.
