tarr is not a list or a data frame. Use.data.frame(tarr) so that it uses the same assumptions as the examples in this thread. I believe there is no such facility due to a philosophical opposition. Unless someone were careful they would naturally assume that boxplots were shown even though that is not the case here. -- 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.
