Thanks Gabor, I'm getting closer.
Is there a way to spread out resp values vertically for a given value of
index? In base graphics, stripchart does this with method = "stack". But
in lattice, stack = TRUE does something rather different, and I don't see a
combination of lattice arguments that does it like base graphics.
Thanks, Bryan
