[Jeff Newmiller]

Suggestions:
a) Don't post in HTML format... your code appears corrupt.
b) Don't do this. Read the Note in ?.First

I hadn't used R (which I usually play with in RStudio) in a few weeks, but when I started up recently and updated (R 3.1.0+ RStudio v 0.98.945),I got a couple error messages.? For context, here is my .First function:
