The 'groups' option doesn't really do anything in any of the high level lattice functions, it just sends the groups variable (and associated subscripts) to the panel function. It is the panel function that needs to know how to deal with that information. As things stand now, panel.qqmath doesn't know what to do with it. More importantly, qqmath is currently structured in a way that would make this very difficult to implement. I don't think there's a good reason for this (other than consistency with S-PLUS) and I would prefer to allow the possibility of grouped Q-Q plots. But this would need a fair bit of restructuring and will certainly not happen before R 2.0.0.
