You could look at R Internals for such a thing, but you wouldn't find
it. (That manual tends to cover lower level issues.)
Generally in a case like this you need to go to the source code. First,
get a copy, then figure out what happens. Here are the steps:
1. Download the full source from
http://cran.r-project.org/src/base/R-2/R-2.12.0.tar.gz (or from a
mirror), and untar it.
2. We use R CMD Rd2dvi to get the output we want. Looking in
src/scripts, you can see that the Rd2dvi script does some argument
cleaning, then runs tools:::..Rd2dvi().
3. Look in src/library/tools/R for the file containing the source to
..Rd2dvi(); you'll find it in Rd2dvi.R.
You can also see deparsed versions just by printing the tools:::..Rd2dvi
function, but they may not be as useful as the original source.
I hope that helps.
