Thanks to Carl, David and Susan for their advice. According to Wikipedia, it is the symbol for a logical *not* gate. Unicode U+00AC. http://en.wikipedia.org/wiki/Negation
The weird part was that I pasted the content directly into R-gui from Gmail and only had issues with extra line breaks (end of a comment on the next line sort of stuff, not invisible new lines). When I pasted it into the script editor to fix the comments and then copy/pasted back to R-GUI, that's when the characters popped up. This is why I emailed, because they weren't there until I edited in the script editor. Unless they were there and they weren't in a position that would cause an error and I messed that up by editing it. Sadly, I've retraced my steps and I can't replicate it this morning. It's almost like it happens randomly or just when I need to get things done. :/ I've downloaded TextWrangler and I'll Zap Gremlins before pasting into R-GUI if I have a problem in the future. Thanks All.
