Dear Prof Ripley,
Thanks for your answer.

Can I invoke compile options if/when I use R cmd install etc. to install
packages?

The situation is this: I pass arguments from R to C, then most of these are
passed on to a Fortran routine, and then the same way back.

I suppose that at the end of the C-routine the arguments are copied back to
R. Where/who or what decides what the length of a vector is that is passed
back to R?

Best, ingmar
