Hello,
I am new to Mac OS having moved off Windows PCs, and I am struggling to figure out how to use R project on the Mac. Often when I enter script into the console, R goes off into a never ending “Not responding” state – the spinning wheel symbol shows.
My usual pattern is that I develop R script in the editor, and then copy the lines I want to run, and paste them into the R Console window. On Mac it sometimes works and other times leads to the spinning wheel. I also have tried using the CMD-Return combination to run the lines with the same results. 
Is there a different recommended way to develop, test, and run scripts on the Mac version?
Is the latest Mac OS release a beta release; should I be using an older version?
Thanks for any advice on how to proceed.
Rick Johnson

My software:
Mac OS X, 10.6.8
R version 2.13.1 (2011-07-08)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)
[R.app GUI 1.41 (5874) x86_64-apple-darwin9.8.0]
