Thanks for pointing out this potential problem. Oh well -- I hoped to have a simple set of instructions, and having everyone install XQuartz followed what I took to be Simon's suggestion (below). Almost all of the problems people have with the Rcmdr package are on the Mac OS X platform, and since most of these people are not sophisticated in their computer use, having simple instructions is important. How about the following? (1) Run System Update. (2) Check whether X-Windows is installed. (I can restore my previous instructions about how to check.) (3) If X-Windows isn't installed, install XQuartz. etc. Best, John . . . > >> > -----Original Message----- > >> > From: Simon Urbanek [mailto:simon.urba...@r-project.org] > >> > >> > Sent: Thursday, September 19, 2013 11:49 AM > >> > To: John Fox > >> > Cc: 'David Winsemius'; 'Sarah Hardy'; 'r-sig-mac' > >> > Subject: Re: [R-SIG-Mac] Problems loading Rcmdr on a Mac 10.7.2 > >> and a > >> > Mac 10.6.8 > >> > > >> > >> > Well, the I think it reads far more complicated that in needs to > >> be. > >> > You should have a quickstart section that just says: > >> > > >> > * Install R 3.0.1 or later > >> > * Install XQuartz from http://xquartz.macosforge.org > >> > > >> > Done.
