A better reference for that is Elements of Graphing Data, where boxplots created after discretizing the x variable is used to motivate lowess. It's pretty much the only legitimate use I have seen of boxplots with shingles (it's a cheap way to get both a sense of location and variability non-parametrically). I vaguely remember seeing an even better reference, but can't find it now. -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.
