Hello everybody, I've a multi-level structured data.frame.
I = Individual Level (factor) G = Group Level (factor) SW= Software (factor) I G SW 1 1 A 2 1 A 3 2 B Im looking for a frequncy-talbe of the used software on the group level. In this case the result has to be: A = 0.5 B = 0.5 Is there an easy way to do things like this or do I have to read myself into Multi-Level Analysis? Thank you Frequencey ______________________________________________ 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.
