     object: any object to which `as.matrix' can be applied.

      value: a matrix, or list of matrices, with the same
             dimensions as `as.matrix(object)' with the new
             values to be assigned to the matrix associated
             with `object'.

        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
        `pdMat', `pdBlocked', and `reStruct'.

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

        will depend on the method function; see the appropriate
        documentation.
