[R] Moving to Mac OS X

[Victor Manuel Garcia Guerrero]

Hi all,
 
I have been using R on Windows for a long time, but now I am ready to move to Mac OS X, but I was just wondering if R works better on Mac than on Windows. This is because I had some memory size issues in the past. 
 
Another question is if some of you know an R editor for Mac (just like Tinn-R).
 
Thanks.
