Remove Installed Packages

Description:

     Removes installed packages/bundles and updates index information
     as necessary.

Usage:

     remove.packages(pkgs, lib, version)

Arguments:

    pkgs: a character vector with the names of the package(s) or
          bundle(s) to be removed.

     lib: a character vector giving the library directories to remove
          the packages from.  If missing, defaults to the first element
          in '.libPaths()'.

 version: A character vector specifying version(s) with versioned
          installs of the package(s) to remove.  If none is provided,
          the system will remove an unversioned install of the package
          if one is found, otherwise the latest versioned install.

Details:

     If an element of 'pkgs' matches a bundle name, all the packages in
     the bundle will be removed.  This takes precedence over matching a
     package name.

     'pkgs' and 'version' will be recycled if necessary to the length
     of the longer one.

See Also:

     'REMOVE' for a command line version; 'install.packages' for
     installing packages.
