If you want to use Fortran programs in R under Unix use
$ R SHLIB -o myprogs.so prog1.f prog2.f prog3.f
$ R> dyn.load("myprogs.so")
[On a very few systems it might need to be .sl not .so.]
If you get no errors, that''s all that is needed *except* interfacing
the
code to R via .Fortran calls. There is quite a bit on that, and it
can be tricky. (S books will help your there, though.)
