       x: An Splus object

gridlist: A list with as many components as variables
          describing the surface.  All components should
          have a single value except the two that give the
          grid points for evaluation. If the matrix or data
          frame has column names, these must appear in the
          grid list.

  extrap: Extraplolation beyond the range of the data.

     ...: Method for specific class of data  may have addi-
          tional arguments.
