Hi all,

I want to create a rather standard overlaid qqnorm plot on a single
variable, with different subgroups of the same dataset plotted using
different colors/symbols/etc. (I don't want side-by-side, rather
different-colored curves on the same graph)

I managed to do it rather tediously using "lapply" and "split", and wondered
whether there is any single-command shortcut. Is there anything on the
"lattice" package perhaps?

Thanks in advance, Assaf
