Write your own panel function, it shouldn't be too hard. Don't expect it to be part of lattice, because I think stacked histograms are a bad idea (use stacked bar charts for factors or grouped density plots for continuous data) and it will not be in lattice for the same reason there are no pie charts. Histograms are bad enough to begin with. -Deepayan ______________________________________________ [EMAIL PROTECTED] 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.
