English language aside, do you want histograms (count frequency) or scatterplots (y~x) ? as David suggested the group argument or '+' combined with allow.multiple is useful, but not trivial for histograms. A simple solution is to consider alternatives such density curves: densityplot(~as.numeric(volcano[,c(2:5)])|cut(volcano[,1],4), groups=gl(4,nrow(volcano)), key=simpleKey(as.character(2:5),points=F,lines=T,columns=4)) In the future, a minimal working example and clear statement of your goal may reduce the need for multiple posts.
