Jared:
I agree with your advice - I use source() too!
I think I work in a different way to many, and don't ever "save
current workspace" but use the interactive R environment cutting and
pasting code from documents held under version control.
As long as one is careful, I don't think there is any problem!
Best wishes,
Mark
