[Rd] Problem with R math library.

Hello.

I've been working on my OCaml-R binding, and I quite pleased to see that it is functional, though far from being perfect or polished. You can find the gitweb webpage and the interface documentation at

	http://yziquel.homelinux.org/gitweb/?p=ocaml-r.git;a=tree
	http://yziquel.homelinux.org/topos/api/ocaml-r/index.html

I'm having unexpected trouble with the math library, though. The interface documentation is here:

        http://yziquel.homelinux.org/topos/api/ocaml-r/Rmath.html

For instance, for the norm_rand symbol, I have the following documentation comment:

> val norm_rand : unit -> float
> Random variates from the standard normal distribution. Bug: currently systematically returns -8.77332116900134373.

Any idea as to why the function systematically returns the same value? Is there a way the math library should be initialised?

All the best,
