I never use R > from a Terminal, so don't know if it occurs or not outside R.app. I figured that the Rcmdr wasn't directly implicated, but my guess was that it was a tcltk issue, so this is very useful information. The problem didn't occur for me outside of R.app, but then I wasn't using the Quartz graphics device. > > It's not related to Rcmdr and you're observation is indeed one of the > better ways to kind of reproduce the issue.

This "works" for me every time: (1) In a fresh R.app session, load the Rcmdr, library(Rcmdr). (2) "Data -> Data in packages -> Read data set from an attached package." Pick any data set. I used Prestige from the car package. (3) Draw any graph on the Quartz device. I used "Graphs -> Histogram" and selected education. Close the Quartz device, and watch the crash. I hope that this proves of some use in diagnosing the problem. > > This issue and sometimes very long sequences of plots (never have > been able to make that reproducible, sometimes the crash happens up > to a minute after R finishes a series of plots and I'm working in an > external editor like TextMate) are hard to pin down. > > Regards, > Rob > > Note: Hope you don't mind I've removed the R-bugs & R-devel Cc's. No -- this is more natural on r-sig-mac.
