Install specified version of a CRAN package.

If you are installing an package that contains compiled code, you will need to have an R development environment installed. You can check if you do by running devtools::has_devel (you need the devtools package for this).

install_version(
  package,
  version = NULL,
  dependencies = NA,
  upgrade = c("default", "ask", "always", "never"),
  force = FALSE,
  quiet = FALSE,
  build = FALSE,
  build_opts = c("--no-resave-data", "--no-manual", "--no-build-vignettes"),
  build_manual = FALSE,
  build_vignettes = FALSE,
  repos = getOption("repos"),
  type = "source",
  ...
)

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.
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.
upgrade	One of "default", "ask", "always", or "never". "default" respects the value of the `R_REMOTES_UPGRADE` environment variable if set, and falls back to "ask" if unset. "ask" prompts the user for which out of date packages to upgrade. For non-interactive sessions "ask" is equivalent to "always". `TRUE` and `FALSE` are also accepted and correspond to "always" and "never" respectively.
force	Force installation, even if the remote state has not changed since the previous install.
quiet	logical: if true, reduce the amount of output.
build	If `TRUE` build the package before installing.
build_opts	Options to pass to `R CMD build`, only used when `build`
build_manual	If `FALSE`, don't build PDF manual ('--no-manual').
build_vignettes	If `FALSE`, don't build package vignettes ('--no-build-vignettes'). is `TRUE`.
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()`.
