_D_e_s_c_r_i_p_t_i_o_n:

     Utility for installing add-on packages.

_U_s_a_g_e:

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

_A_r_g_u_m_e_n_t_s:

    pkgs: A space-separated list with the path names of the packages to
          be installed.

     lib: the path name of the R library tree to install to.

 options: a space-separated list of options through which in particular
          the process for building the help files can be controlled. 
          Options should only be given once. Use 'R CMD INSTALL --help'
          for the current list of options. 

_D_e_t_a_i_l_s:

     This will stop at the first error, so if you want all the 'pkgs'
     to be tried, call this via a shell 'for' or 'foreach' 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 'R_LIBS' for duration of the
     install, so required packages in the installation directory will
     be found (and used in preference to those in other libraries).

     Both 'lib' and the elements of 'pkgs' may be absolute or relative
     path names of directories.  'pkgs' may also contain names of
     package/bundle archive files of the form 'pkg_version.tar.gz' as
     obtained from CRAN: these are then extracted in a temporary
     directory.  Finally, binary package/bundle archive files (as
     created by 'R CMD build --binary' can be supplied.

     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 configure variables 'LIBS' and '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, only the last instance is used.)  One can bypass the
     configure mechanism using the option '--no-configure'.

     If '--no-docs' is given, no help files are built.  Options
     '--no-text', '--no-html', and '--no-latex' suppress creating the
     text, HTML, and LaTeX versions, respectively.  The default is to
     build help files in all three versions.

     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.

     Use 'R CMD INSTALL --help' for more usage information.

_P_a_c_k_a_g_e_s _u_s_i_n_g _t_h_e _m_e_t_h_o_d_s _p_a_c_k_a_g_e:

     Packages that require the methods package, and that use functions
     such as 'setMethod' or 'setClass', should be installed either
     (preferably) using lazy-loading or by creating a binary image: use
     the flags 'LazyLoad' and 'SaveImage' in the 'DESCRIPTION' file to
     ensure this.

_S_e_e _A_l_s_o:

     'REMOVE' and 'library' for information on using several library
     trees; 'update.packages' for automatic update of packages using
     the internet (or other R level installation of packages, such as
     by 'install.packages').

     The section on "Add-on packages" in "R Installation and
     Administration" and the chapter on "Creating R packages" in
     "Writing R Extensions" (see 'RShowDoc' and the 'doc/manual'
     subdirectory of the R source tree).
