Much thanks to everyone for their recommendations! I agree that fishing in the
global environment isn't ideal & only shows my budding understanding of R.
For now, I will adapt Chel Hee's "length(eval(parse(text=DFName))[,1])"
solution then fully explore Jeff's suggestion to put the data frames

I like Jeff's comments on the previous post.
Regarding Alan's question, please see the following example.

This approach is fraught with dangers.
I recommend that you put all of those data frames into a list and have your
function accept the list and the name and use the list indexing operator
mylist[[DFName]] to refer to it. Having functions that go fishing around in the
global environment will be
