The problem I face is you have used too many "..."'s, and "etc"'s and
not enough R code. You probably have a clear idea what "summary
statistics by crossing numerous variables 2x2 AT ONCE" means but I do
not. It is possible that the describe.formula in Hmisc or the
summaryBy function in the doBy package may be helpful, but that is
merely a guess.
