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.
