Well, you have essentially two options:
1. Rewrite your main program as an R function, from which you call the
subroutines (thru the .Fortran interface).
2. Rewrite your main program as a Fortran subroutine, write an R wrapper,
that calls your new subroutine (thru the .Fortran interface).
Choose whatever is simplest.
