Thank you Jim, for the code, and thank you Jeff for the tutorial PDF. I've read through the sections and I appreciate the help. I'm in way over my head - I don't even understand enough of the vocabulary to ask my question correctly. Jim, in your code, I ended up with an entry of 4 observations of 6 variables. I understand how that happened now since I read your code - that helped very much. My only problem, that I can't figure out, is how to make it so I have 3 raters with 4 observations of 6 variables. I really am trying to educate myself enough to not waste your time: I've ?data.frame, ?sample, ?matrix, ?$names, ?attributes, etc... I read the sections in Jeff's PDF, and the tutorials on datamentor, I'm just not finding how to do this. I'm sorry this is such a newbie question. thank you for your time, hallie
