Eric may have more to say, but the straightforward answer is: use functions
to do what you want and pass any file specific info to them as parameters
of function calls.

If this seems arcane to you, then you have some homework to do, as using
functions is a (maybe the) central programming paradigm in R. Numerous
tutorials elaborate on this.

If I have misunderstood, my apologies, and just disregard.
