Help with OCaml bindings for R interpreter.

Hello.

I've made out a Debian package out of Maxence Guesdon's OCaml/R  
bindings:

	http://yziquel.homelinux.org/topos/debian-ocamlr.html
	http://yziquel.homelinux.org/debian/pool/main/o/ocaml-r/

The upstream software itself is on the following page:

	http://home.gna.org/ocaml-r/

This binding is dynamically linked to the /usr/lib/R/lib/libR.so and  
to
the /usr/lib/libRmath.so libraries. Its purpose is to access R
functionalities from OCaml programs.

However, as it now stands, the binding is not fully functional: When  
an
OCaml program is compiled with this binding, to generate, say,
myprog.byte, it is necessary to run

	R CMD ./myprog.byte

in order for the program to work as expected. I would therefore like  
to
know how to *completely* embed the R interpreter inside my binding.

Could anyone provide generic information on this topic, or point me to
the right documentation?

All the best,

It *is* completely embedded. R CMD simply sets up the correct 
environment for the current R.

For a given, specific R installation you 
could re-create the environment in the executable (see R CMD sh -c set), 
but by definition it is specific for that installation so you'd have to 
compile that binary at install time.
