Hi, Coming to R from SAS...
I have a data.frame A with 2 long factors "x" and "y". I want to get a count of the number of rows with each level of "x" and "y" jointly. 'table' seemed like it would work, but as I have many levels, the matrix output is pretty useless to me (and I don't care about zero values). How can I get output that looks like: A$x A$y Freq ------ ----- ------- x1 y1 8 x1 y3 10 ... Thanks a ton, Matt -- It is from the wellspring of our despair and the places that we are broken that we come to repair the world. -- Murray Waas ______________________________________________ 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.
