        apropos(pattern, where=FALSE)

   AArrgguummeennttss::

    pattern: a regular expression to match against

      where: a logical indicating whether positions in the
             search list should also be returned

   DDeessccrriippttiioonn::

        `apropos' returns a vector of character strings giving
        the names of all objects in the search list matching
        `pattern'.  If `where' is `TRUE', their position in the
        search list is returned as their names attribute.

        `objects' for listing objects from one place, `search'
        for the search path.
