Yes, I thought maybe Thomas needed to say where.  You need the packages
grid and lattice from the Devel section on CRAN, and you had better be
using 1.3.0 (which is what I assume you mean by R-1-3).

Both grid and lattice are under development, which is why they are in
Devel.  You may need a description of S's Trellis to get an overview of
what lattice is intended to do, but don't expect perfect equivalence
(especially not yet).
