If I had a large program that I needed to run just once, e.g. an 
analysis or simulations for a paper, here's how I would organize it:

  - Identify all the general purpose functions and put them in a package.
  - The one-off parts of the code don't really belong as functions in a 
package, though there's nothing to stop you from doing that.  I'd 
probably put them into a vignette, or just write the whole paper in 
Sweave, which is almost the same thing.

If your general purpose functions do something new that would be useful 
to others, you might want to polish up the package and send it to CRAN 
(and perhaps submit it with a supporting paper to JSS).  But that's not 
necessary:  a package is a good way to organize code for your own use too.
