Dependency plot - should ignore text in comments

[enginuity]

Check to see if this is still a problem, since supposedly comment ignoring is now possible.

This is a problem because it will search comments for function names, which is bad. In general, this might warrant being fixed more generally (but need to look very carefully for #'s, as they may appear inside quotations or whatnot). Perhaps there needs to be a R code parser more generally?

Might be worthwhile to look around for an R code parser, since presumably something like this may already exist.

Want to examine the use of R parse function, or related functions, here.
