Sarah, note that 10.7.2 is way old - there have been many patch releases since then so first thing I'd suggest is to run Software Update. XQuartz doesn't remove system X11 if installed, so it's not necessarily relevant (it depends on the local setup) - OS updates may be more important here.

Dear Simon, Thank you very much for these clarifications (and also for responding to David and Sarah's posts in this thread). I think that I understand what's going on now, and will add a note to the Rcmdr installation instructions to run Software Update prior to installing R, the Rcmdr, and (if

Dear Simon, OK -- thanks for the further clarification. If you can bear with me a bit longer, I've drafted an update to the Rcmdr installation notes, the relevant part of which now reads as follows -- [link] represents a hyperlink: -- snip --- . . . These instructions

Thank you John, David and Simon for your helpful posts. John - I think your instructions were revised after I sent my coursepacks to the printers. I base my instructions on yours, but take out the parts about inserting the Mac OS X install disc because the probability my students (75 mostly

Dear Simon, That's a good suggestion. In fact, I don't see a real function for the technical details, so I've just eliminated them. I also think that adding the step to run Software Update is harmless and a good idea, so I've added that. The full set of instructions (including the parts that I

Running the Software Update and reinstalling R and Rcmdr worked for the student with the 10.7.2. We did not reinstall XQuartz. Now I will see if it works for the others. BTW - I have identified at least one student with a 10.6.8 who had no problems installing R and Rcmdr without installing XQuartz
