## Install Add-on Packages

### Description

Utility for installing add-on packages.

### Usage

    R CMD INSTALL [options] [-l lib] pkgs

### Arguments

`pkgs` | a space-separated list with the path names of the packages to be installed. See ‘Details’.
`lib` | the path name of the R library tree to install to. Also accepted in the form --library=lib. Paths including spaces should be quoted, using the conventions for the shell in use.
`options` | a space-separated list of options through which in particular the process for building the help files can be controlled. Use `R CMD INSTALL --help` for the full current list of options.

### Details

This will stop at the first error, so if you want all the `pkgs` to be tried, call this via a shell loop.

If used as `R CMD INSTALL pkgs` without explicitly specifying `lib`, packages are installed into the library tree rooted at the first directory in the library path which would be used by R run in the current environment.

To install into the library tree `lib`, use `R CMD INSTALL -l lib pkgs`. This prepends `lib` to the library path for duration of the install, so required packages in the installation directory will be found (and used in preference to those in other libraries).

It is possible that environment variable TMPDIR will need to be set (although `R CMD` tries to set it suitably otherwise): use forward slashes and no spaces for the path to a writable directory.

Both `lib` and the elements of `pkgs` may be absolute or relative path names of directories. `pkgs` may also contain names of package archive files: these are then extracted to a temporary directory. These are tarballs containing a single directory, optionally compressed by `gzip`, `bzip2`, `xz` or `compress`. Finally, zipped binary packages (as created by `R CMD INSTALL --build`) can be supplied.

Tarballs are by default unpackaged by the internal `untar` function: if needed an external `tar` command can be specified by the environment variable R_INSTALL_TAR: please ensure that it can handle the type of compression used on the tarball. (This is sometimes needed for tarballs containing invalid or unsupported sections, and can be faster on very large tarballs. Setting R_INSTALL_TAR to tar.exe has been needed to overcome permissions issues on some Windows systems.)

The package sources can be cleaned up prior to installation by --preclean or after by --clean: cleaning is essential if the sources are to be used with more than one architecture or platform.

If the attempt to install the package fails, leftovers are removed. If the package was already installed, the old version is restored. This happens either if a command encounters an error or if the install is interrupted from the keyboard: after cleaning up the script terminates.

For details of the locking which is done, see the section ‘Locking’ in the help for `install.packages`.

Option --build can be used to zip up the installed package for distribution.

By default a package is installed with static HTML help pages if and only if R was: use options --html and --no-html to override this.

Packages are not by default installed keeping the source formatting (see the `keep.source` argument to `source`): this can be enabled by the option --with-keep.source or by setting environment variable R_KEEP_PKG_SOURCE to `yes`.

Use `R CMD INSTALL --help` for concise usage information, including all the available options.

### Sub-architectures

An R installation can support more than one sub-architecture: currently this is most commonly used for 32- and 64-bit builds on Windows.

For such installations, the default behaviour is to try to install source packages for all installed sub-architectures unless the package has a configure script or a ‘src/Makefile’ (or ‘src/Makefile.win’ on Windows), when only compiled code for the sub-architecture running `R CMD INSTALL` is installed.

To install a source package with compiled code only for the sub-architecture used by `R CMD INSTALL`, use --no-multiarch. To install just the compiled code for another sub-architecture, use --libs-only.

There are two ways to install for all available sub-architectures. If the configure script is known to work for both Windows architectures, use flag --force-biarch (and packages can specify this via a Biarch: yes field in their `DESCRIPTION` files). Second, a single tarball can be installed with

    R CMD INSTALL --merge-multiarch mypkg_version.tar.gz

### Staged installation

The default way to install source packages changed in R 3.6.0, so packages are first installed to a temporary location and then (if successful) moved to the destination library directory. Some older packages were written in ways that assume direct installation to the destination library.

Staged installation can currently be overridden by having a line StagedInstall: no in the package's ‘DESCRIPTION’ file, via flag --no-staged-install or by setting environment variable R_INSTALL_STAGED to a false value (e.g. false or no).

Staged installation requires either --pkglock or --lock, one of which is used by default.

### Note

The options do not have to precede pkgs on the command line, although it will be more legible if they do. All the options are processed before any packages, and where options have conflicting effects the last one will win.
