R help - Sep 2008 - include scripts into main file (the LaTeX way)

Dear R-people,

I want to use an idea from LaTeX in the work flow with R.
It is possible in LaTeX to have a main file from which other files are 
called (ie included).
So for example if you have book, the main index file would call each 
chapter separately.

Is there something comparable in R that follows the above 'include' idea
from LaTeX?
A main file that calls parts of an analysis or data preparation separately.

Thanks!
Michael

Perhaps ?source.

I've used source() for that.

This is hardly original to LaTeX (in fact even TeX has a way), and most 
programming languages have such a mechanism (e.g. #include in C).

R's nearest equivalent is source(), but that does not have a mechanism 
like TEXINPUTS to search for files (but then neither does MikTeX).  I 
believe I have seen a search implementation for source(), but R's package 
mechanism makes it much less necessary.

Whereas in R you have functions and packages to encapsulate useful pieces 
of code.
