Thanks you for the suggestions. It seems I will use R often afterwards, so I will study the manuals and commands little by little. I do not reject the command line geek style, but the beginning steps and basic functions should be easy. Your Rcmdr offered this to new users; without it, I won't begin to learn and use R.

Your observations of my posted image are correct. So that is my expectation of grouped QQ plot. I hope it will come to Rcmdr soon. Also, thanks Google, I find a way to do that:

That shape or color grouping in one chart is exactly what I need. Although I don't quite understand the commands used, I think I can copy and modify the commands a little to do my work. Could you incorporate it in the Rcmdr? Maybe consider it in your spare time.
