Install Add-on Packages
Utility for installing add-on packages.
R CMD INSTALL [options] [-l lib] pkgs
- a space-separated list with the path names of the packages to be installed. See Details.
- 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.
- a space-separated list of options through which in
particular the process for building the help files can be controlled.
R CMD INSTALL --helpfor the full current list of options.
This will stop at the first error, so if you want all the
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
R CMD INSTALL -l lib pkgs.

directory will be found (and used in preference to those in other
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
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
Finally, binary package archive files (as created by
R CMD INSTALL --build) can be supplied.
Finally, zipped binary packages (as created by
R CMD INSTALL --build) can be supplied.
Tarballs are by default unpackaged by the internal
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. unix
Some package sources contain a configure script that can be
passed arguments or variables via the option --configure-args
and --configure-vars, respectively, if necessary. The latter
is useful in particular if libraries or header files needed for the
package are in non-system directories. In this case, one can use the
CPPFLAGS to specify these
locations (and set these via --configure-vars), see section
Configuration variables in R Installation and
Administration for more information. (If these are used more than
once on the command line they are concatenated.) The configure
mechanism can be bypassed using the option --no-configure.
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

Option --build can be used to tar up the installed package
for distribution as a binary package (as used on OS X). This is done

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.

environment variable R_KEEP_PKG_SOURCE to
R CMD INSTALL --help for concise usage information,
including all the available options.
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. unix
Some parts of the operation of
INSTALL depend on the R
temporary directory (see
tempdir, usually under
/tmp) having both write and execution access to the account
running R. This is usually the case, but if /tmp has been
noexec, environment variable TMPDIR may need
to be set to a directory from which execution is allowed.
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
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 field in their
Second, a single tarball can be installed with
R CMD INSTALL --merge-multiarch mypkg_version.tar.gz
.libPaths for information on using several library trees;
install.packages for R-level installation of packages;
update.packages for automatic update of packages using
the Internet or a local repository.
