[R] R and Fortran

[Prof Brian Ripley]

Are you serious, reporting on a 2004 version of R?  Please do as the 
posting guide requested, and update your R.  (Only posting one copy is 
also appreciated around here.)

Beyond that, normally foo.o is not a shared library but a compiled object. 
You have not told us what you did, and probably the issue is that you 
don't know how to make a shared library from Fortran.  Please ask your IT 
advisers about that (and hint, R CMD SHLIB may help you).
