[R] programming advice?

[Charles Annis, P.E.]

Dear R-helpers:

I am doing some exploratory programming and am considering a routine that
has several other routines defined within it, so that I can avoid a large
and messy global re-programming to avoid naming conflicts.  

My question is this:  Because it is interpreted, does R have to re-build
these internal routines every time the new routine is called?  I'm not
overly worried right now about speed, but since my test cases currently run
for several minutes (which is a long time to me) I don't want to learn a
lesson the hard way that you, kind readers, might help me avoid.

Thanks.
