Bill's example shows how to do it with a list of numeric vectors. Here is another example using the built in anscombe and making use of my prior code, Bill's and Vining's: bp <- boxplot(anscombe, plot = FALSE) bp$stats <- sapply(anscombe, function(x) c(min(x), mean(x) + c(-1, 0, 1) * sd(x), max(x))) bxp(bp, outline = FALSE) -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ 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.
