If you are willing to (install and) use "R-devel",
Luke Tierney has written a package "codetools" which does
what you want, at least gives you the building blocks:
You need R-devel (which will become R 1.8 in October):

If you are not an R "newbie"
the package __IN SOURCE FORM__ (i.e. not compiled for Windows!)
can be downloaded from
http://www.stat.uiowa.edu/~luke/R/codetools/
(Again: You need R-devel, and need to be able to install
packages from source!)
