I see your points, but I am looking at ESS (which is loading .R files as
well into the ESSR environment) and whose loading mechanism I want
to piggy back the loading of .R for org. If I understand the variable
transfer from org to R correctly, it anyway only works on local R
sessions, which makes it even easier to do then ESS which also caters
for remote R sessions.
My idea is to have all R code in one directory and to let ESS load it
upon initialization of ESS (which is a dependency of running R from org
anyway, if I am not mistaken). I have a prototype working, and will keep
you posted. The complication would be that a newer version of ESS would
be needed.
The other option would be to just copy the code ESS uses into org, which
would make the process independent of changes in ESS. But I don't like
the duplication of code.

I would suggest in a etc/R.

True - but I like the simplicity of being able to customize the
behavior of org-babel-R by writing an R function without having to thin
about elisp. But maybe there is a way of doing both...
Thanks for your comments,
