And I thought a binding would be easier to use. Printing/parsing becomes tedious.

Because - Printf-ing the code is kind of heavy and error-prone, - parsing the computed values is some work to handle correctly, - the compiler can't tell me if I did something wrong so I get all the errors at execution time.

This need not be the case if you apply language embedding/meta- programmation techniques (see for example [1]). You can even mask R computations behind plain caml functional types. I have an unpolished toy example that does this to program arithmetic functions on regular ocaml types but that use scsh to actually compute the result (no camlp4 or unsafe features required), I can forward it to you if you are interested. Here's an example of a polymorphic cube function, when you invoke cubei or cubef the result will actually be computed by scsh. The drawback is that you need to "write" the type your functions by hand (cf argi argf reti retf). open Mini open Override open Program let cube_s = fun x -> x * x * x let cubei_p = compile (argi (reti cube_s)) let cubef_p = compile (argf (retf cube_s)) let cubei : int -> int = as_fun cubei_p let cubef : float -> float = as_fun cubef_p However as Ashish pointed out the biggest problem are the data sets, but it may be that you can keep them in R only with suitable types to represent them in ocaml.
