Download a specified version of a CRAN package

It downloads the package to a temporary file, and returns the name of the file.

download_version(
  package,
  version = NULL,
  repos = getOption("repos"),
  type = getOption("pkgType"),
  ...
)

Arguments

package	package name
version	If the specified version is NULL or the same as the most recent version of the package, this function simply calls `utils::install.packages()`. Otherwise, it looks at the list of archived source tarballs and tries to install an older version instead.
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.
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.
...	Other arguments passed on to `utils::install.packages()`.

Name of the downloaded file.
