produces a barplot very fine. In addition, I'd like to get the bars'

barplot() returns a vector of midpoints so you can use text() to add the annotation. There is an example in the manual page of barplot: mp <- barplot(VADeaths) tot <- colMeans(VADeaths) text(mp, tot + 3, format(tot), xpd = TRUE, col = "blue") cu Philipp
