Given this example mean.values<-colMeans(VADeaths)
mean.values<-apply(VADeaths, 2, mean) median.values<-apply(VADeaths, 2, median) dotchart(VADeaths, gdata=mean.values) dotchart(VADeaths, gdata=median.values) is it possible to “combine” a single dotchart showing both the mean and the median for each single group (with different plotting symbols)? …is it that possible with the use of the standard graphics or it is necessary (better) to use of a different package? Any example for this in my favourite (even almost always too much complex for myself) package lattice? thank you -- View this message in context: http://r.789695.n4.nabble.com/Dotchart-showing-mean-and-median-by-group-tp4619597.html Sent from the R help mailing list archive at Nabble.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.
