[R] Storing and managing custom R functions for re-use

[Simon Chamaillé-Jammes]

Dear all,

sorry if this is a bit on the sidetrack for R-help.

As a regular R user I have developed quite a lot of custom R functions, 
to the point of not always remembering what I have already programmed, 
where the file is and so on.
I was wondering what other people do in this regards. A basic file with 
all your functions, or a custom R package, or directly integrated into a 
profile file ??? I'm considering that a blog with tagged posts may be a 
good solution (and really good ones could join R-bloggers maybe).

If someone is happy to share what (s)he considers good practice, thanks.
