[Rd] R worked once, now will not open. Works in console, but won't graph. (PR#7953)

Richard,

thank you for the report. From the log it seems to be a problem with  
your preferences. Please delete the file ~/Library/Preferences/org.R- 
project.R.plist (e.g. type
rm  ~/Library/Preferences/org.R-project.R.plist
in Terminal or simply delete than file using Finder) and let me know  
if that fixes the problem (actually if it's easy for you to do you  
could send me the file before you delete it if it turns out to be the  
problem). In addition you may want to download the latest version of  
R.app from http://www.rosuda.org/R/nightly/ .

Cheers,
Simon
