     'library.pos' loads add-on packages, allowing specification of
     position in the search path.

_U_s_a_g_e:

     library.pos(package, help, pos = 2, lib.loc = NULL, character.only = FALSE,
                 logical.return = FALSE, warn.conflicts = TRUE,
                 keep.source = getOption("keep.source.pkgs"),
                 verbose = getOption("verbose"), version)

_A_r_g_u_m_e_n_t_s:

package, help: name or character string giving the name of a package.

     pos: the position on the search list at which to attach the loaded
          package. Note that '.First.lib' may attach other packages,
          and 'pos' is computed _after_ '.First.lib' has been run.

 lib.loc: a character vector describing the location of R library trees
          to search through, or 'NULL'.  The default value of 'NULL'
          corresponds to all libraries currently known.

character.only: a logical indicating whether 'package' or 'help' can be
          assumed to be character strings.

 version: A character string denoting a version number of the  package
          to be loaded.  If no version is given, a suitable default is
          chosen.

logical.return: logical.  If it is 'TRUE',  'FALSE' or 'TRUE' is
          returned to indicate success.

warn.conflicts: logical.  If 'TRUE', warnings are printed about
          'conflicts' from attaching the new package, unless that
          package contains an object '.conflicts.OK'.

keep.source: logical.  If 'TRUE', functions ``keep their source''
          including comments, see argument 'keep.source' to 'options'.

 verbose: a logical.  If 'TRUE', additional diagnostics are printed.

_D_e_t_a_i_l_s:

     This function is backported from the R 1.8.0 development tree and
     is  only defined by gregmisc if this package is loaded in an
     earlier version of R.  In 1.8.0, this function is merely an alias
     for the standard 'library' function.  The only important
     difference is the addition of the "pos" argument which allows an
     imported package to be loaded further down the search path than
     the top entry.

     See the documentation for 'library' for more details.
