I think the next reply i recieved points me to a good solution. -- View this message in context: http://r.789695.n4.nabble.com/boxplot-help-tp4640360p4640392.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.
