[R-SIG-Mac] R crash on startup in OS X

Hi Steve,

Thanks for the quick reply.  The Framework folder and contents are all there at /Library/Frameworks/R.framework/Versions/2.9, including the library file (libR.dylib).  For some reason, however, R still won't load that library and crashes on launch.  

I'm not sure why that would be.  Do you have any other suggestions?

Thanks for your time,

Perhaps I'm misunderstanding you, but I'm not sure how this is possible?

Your new version of R (2.9.2) is installed in precisely that  
folder ... the R.app file in your ../All Things Academic/../.. is  
simply referencing the R "system" installed in /Library/Frameworks/ 

So, in short, you need /Library/Frameworks/R.framework/Versions/2.9  
and its contents to be there to have a working R on your system.

Does that help?
