Right, thanks. The error message might be a tad more illuminating, I think. ;-) Just adding something like "Check to see whether R is already defined."
One more quick question, how do I add a notebook. I go through all the steps, but it doesn't appear in this message.
It says I have to be logged into the "Wolfram Cloud with your community account". I'm still trying to figure out how to do that. I have a Mathematica Home license.
I hope the notebook got added this time.
