[Rd] Using Fortran 95 in an R package?

[John Fox]

Dear R-devel list members,

What's the best current advice about writing Fortran code for use in R
packages? The Writing R Extensions manual still says that the .Fortran
interface is primarily intended for FORTRAN 77 code. In particular, are
there portability issues if I use Fortran 95 in a package? For example, I
see that Rtools for Windows now include the gfortran compiler.

(I know that this question has come up before, but not, as far as I can see,
in the last year.)

Thanks,
 John
