Posted this link


last week. I found this quite simple to follow, so it might be a useful
companion to the Writing R Extensions manual already suggested. The link
above doesn't specifically address fortran 90, but if special handling
of f90 code is required, the Writing R Extensions manual will tell you
what needs to be done differently.
