R help - Jun 2010 - Sweave with external R code

Hello,

I'm new to R and Sweave and I was wondering whether you can just include all
your R code in external files and then call them from within the code chunks.
I've read the Sweave User Manual but I couldn't find any specific
information about this. Is this not customarily done?

Thanks,

-Gaston

Normally the idea is that the Sweave document is self-contained, so you 
wouldn't do this.  However, you would often put a lot of your code into 
a package, and then attach the package early in the Sweave document.  
It's also possible to use source() in a code chunk.
