[Rd] Samples of external code with various compilers?

[Duncan Murdoch]

R can run external code in C, C++, Fortran, Delphi, etc., but the R
extensions manual only gives limited documentation for anything but C
and C++.  It would be useful to have a collection of sample code
showing how to dyn.load functions written in other languages, if
necessary for a variety of different compilers, in case that makes a
difference.

Does such a collection already exist?  If not, would it be better to
put it into the R extensions manual as a series of appendices, or just
have a web page about it?

I'd volunteer to maintain the web page to hold the samples.
