Recovering from R hangs/crashes -

when working in R.  I use "standard" R with the R GUI from CRAN.  Instead
of seeing the list of available files, an empty window appears along with
the dreaded spinning beach ball.  At this point I have to go to the Finder
and force R to quit.

I added the following function to my .bashrc file:

function fixRhang()
{
cd ~/Library/Saved\ Application\ State
rm -R org.R-project.R.savedState/
cd
rm .Rhistory
}

After I force R to quit, I open an XQuartz window, and just enter

bash-3.2$ fixRhang

At this point, I can open R again and continue working (though obviously
the command history is empty).

I'm sure that there are better (or more efficient) ways of accomplishing
this, but it works for me.

Barry,

thanks to your crash report I think that particular issue should be
hopefully fixed (it took me a while to reproduce as you need a big-enough
script open so it changes the margins plus you need to have doc restore
enabled). Please try out R 3.3.3 (if CRAN is not synced yet you can use
http://r.research.att.com/bin/macosx/R-3.3.3.pkg directly) - make sure is
says "R.app GUI 1.69 (7328)".

Thanks,
Simon
