HI,

try to use 'print.trellis()'

Actually the preferred approach is to use print(), not
print.trellis().  That is, call the generic function, not the specific
name of the method.  With namespaces, available in R-1.7.0 and later,
package authors have the option of hiding direct access to methods.
If Deepayan Sarkar added a namespace to the lattice package (and I
think he does plan to do that at some point) then using print() would
work as expected but using print.trellis() would no longer work.
