Ranjan Maitra Posted this link http://www.stat.umn.edu/~charlie/rc/ 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.
