# Personally, this looks more informative to me: library(lattice) bwplot(len ~ supp | factor(dose), data=ToothGrowth, layout=c(3,1)) # and some people like this: require(Hmisc) bwplot(supp ~ len | factor(dose), data=ToothGrowth, layout=c(3,1), panel=panel.bpplot, datadensity=TRUE) -- Dylan Beaudette Soil Resource Laboratory http://casoilresource.lawr.ucdavis.edu/ University of California at Davis 530.754.7341 ______________________________________________ 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.
