R: Install specified version of a CRAN package.

install_version {remotes} | R Documentation

## Install specified version of a CRAN package.

### Description

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).

### Usage

    install_version(package, version = NULL, dependencies = NA,
      upgrade = c("ask", "always", "never"), force = FALSE,
      quiet = FALSE, build = FALSE, build_opts = c("--no-resave-data",
      "--no-manual", "--no-build-vignettes"), 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.
`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 "ask", "always" or "never". "ask" prompts the user for which out of date packages to upgrade.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` 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()`.
