Hi Simon,
This may or may not be good practice, but once I worked out how to make 
packages (see any of the tutorials on this), I just made a little 
package for each group of functions. Three of them grew up to be 
packages on CRAN, so it worked well for me. I think having the functions 
segregated into packages with an easy to recognise theme like the 
<blatant advertisement> clinsig package </blatant advertisement>, helps 
to organize the work for later use.
