You really need to put these in a package.  Besides being an organized 
place to hold code, packages have all sorts of documentation support. 
You'll be able to browse your help pages to see what you've already got, 
what the arguments mean, etc.

Of course, writing good documentation is harder than writing minimal 
documentation, but R (almost) does the latter for you, so it's hardly 
more difficult than writing none at all, but it's a lot more useful.
