Just to add to Jim's remarks... I found that if you have at least 1GB or RAM, and you are running firefox with multiple tabs (or any other software that uses lots of RAM), R cannot do what it wants. If you have just enough ram for what you want to do, try closing down all other applications lest you run into this error. Tony On Thu, May 15, 2008 at 2:32 PM, James W.
