[R] including Sweave tangled code in '.Rnw' document

[Ista Zahn]

You could achieve this from the LaTeX side of things using the
attachfile package:
http://www.ctan.org/tex-archive/macros/latex/contrib/attachfile/

I use this package to attach data files and R code to pdf's generated
with Sweave + pdflatex, so that the entire analysis can be reproduced
from a single document.
