Presuming that your object above is a data frame, you can add a new column using cbind(): > tab X V1 V2 1 A 2 3 2 B 1 6 3 C 4 6 > cbind(tab, TOT = tab$V1 + tab$V2) X V1 V2 TOT 1 A 2 3 5 2 B 1 6 7 3 C 4 6 10 See ?cbind. For actual R tables, you can use ?addmargins HTH, Marc Schwartz ______________________________________________ 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.
