[R-SIG-Mac] Problems with Rcmdr via XQuartz on OSX Mavericks

[John Fox]

Dear Jonathan et al,

First, thank you to all who responded. As I said, I haven't noticed this problem myself, but I'll try again on my Mac later today when I have some time and see whether I can reproduce it. I suspect that this is a tcltk-related issue, not specific to the Rcmdr, but I don't know that for sure.

In the meantime, here are two things to try:

(1) Reijo Sund suggested trying to run R and the Rcmdr from the command line (i.e., in a terminal window), to see whether the problem manifests itself there. The Rcmdr doesn't need R.app. 

(2) It's possible that the slowdown is caused by the way that the Rcmdr handles R Markdown documents. The overhead gets greater as the session proceeds. To test this possibility, you could suppress the R Markdown tab (via the Rcmdr Tools -> Options menu, Output tab -- uncheck the box for R Markdown) and see whether the problem disappears.

Please let me know what happens.

Best,
 John

Rcmdr runs slowly, more-so as a lag, after an initial 1-2 minutes of use.  Prior to that 1-2 minutes of use and the subsequent lag in performance, Rcmdr runs perfectly fine via XQuartz.  Once closing out XQuartz and restarting it, Rcmdr runs fine until after 1-2 minutes of use when the lag sets in again.
