table works with numerics: table(c(1,1,3,4,12,123,12,2,21,2,2,2)) 1 2 3 4 12 21 123 2 4 1 1 2 1 1 Dieter ______________________________________________ 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.
