We need a reproducible example. My guess is that you might use some combination of indexing and the table function, but if you can give us code that shows us a basic example of your setup, that would be great. ______________________________________________ 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.
