     object: any object for which dimensions can be extracted.

        ...: some methods for this generic function require
             additional arguments.

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

        This function is generic; method functions can be writ-
        ten to handle specific classes of objects. Classes
        which already have methods for this function include:
        `corSpatial', `corStruct', `pdCompSymm', `pdDiag',
        `pdIdent', `pdMat', and `pdSymm'.

   VVaalluuee::

        will depend on the method function used; see the appro-
        priate documentation.

   NNoottee::

        If `dim' allowed more than one argument, there would be
        no need for this generic function.
