The documentation of xyplot could be improved here. It says:
"If 'index.cond' is a list, it has to be as long as the number of conditioning
variables, and the 'i'-th component has to be a valid indexing vector for the
integer vector '1:nlevels(g_i)' (which can, among other things, repeat some
of the levels or drop some altogether)."
It should make explicit that nlevels is the number of levels actually
used in the data and not length(levels(f)).
It does say "... _valid_ indexing vector ..." (my emphasis).
If nlevels(g) = 5, but you're only plotting 3 panels, it seems
to me that c(3,1,5) might be a valid indexing vector.
