You need to tabulate your data first; barchart() won't do that for you. Start with barchart(xtabs(~Factor1 + Factor2, your.data)) and try using as.data.frame(xtabs(~Factor1 + Factor2, your.data)) as the data= argument for more flexibility. -Deepayan ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
