I didn't get it at first as I'm not familiar with noweb, but after
reading a bit, I think I get it.

Gotcha. So I can define a preamble/postamble and be all set. Still
struggling on how to make this work for each file, though. I'm
guessing I need something like:

#+name: preamble
#+begin_src R :exports none
tikzDevice("file-name")
#+end_src

And by the org-mode Babel documentation it looks like I can do something like:

<<preamble(file-name=file_1.tex)>>

Or something like this? I didn't see much coverage explaining the
whole <<example-block(a=9>> bit at the end of the noweb section:
- http://orgmode.org/worg/org-contrib/babel/intro.html#literate-programming

I think this will work; I just need the bit on variable substitution.


Thanks a ton!
John
