This seems to be different question than what you later requested. This
question would seem to be documented in the 'panel' section of help(xyplot) in
particular the paragraph beginning with this sentence:
"One can also use functions called panel.number and packet.number, representing
panel order and packet order respectively, inside the panel function (as well
as the strip function or while interacting with a lattice display using
trellis.focus etc). "
