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?
