Jim and all, Thanks for the suggestion, however, I get the following error:
> barplot(t(combine86[,1:2], beside = TRUE, las = 1)) Error in t(combine86[, 1:2], beside = TRUE, las = 1) : unused argument(s) (beside = TRUE, las = 1) I've looked up ?t and cannot see any extra arguments that I should be including, and the executes without the 't'. What is it that I've omitted that I need to successfully execute the code (as previously described)? Many thanks again, Steve _________________________________________________________________ [[elided Hotmail spam]] ______________________________________________ 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.
