use par(las = 3) bxp <- boxplot(df,las = 1,col = "light blue") to control label orientation and access the data displayed in the boxplot (see `?par', `?boxplot') use text(x, y, 'some_text_or_number') to add text to the boxplot. for x, use the 'number of the box' (i.e. `1' in the example above). for y use the mean or median or whatever you wanted). joerg ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
