The `R Language Definition' manual has a chapter `Functions' with a section
`Evaluation' (Sec. 4.3 in the PDF version).  That might be helpful for you.
Also, Thomas Lumley wrote a `Programmer's Niche' column in the R News on how
to get the effect of macros in R.  You might be interested in that, too.

Cheers,
