[R] How can I call R from Java or C?

[Aylin Yilmaz]

Hi,

Thanks for the reply.
I develop on Linux and the production will be on Unix.

I just looked at SJava on OmegaHat.
Yes, I think this is what I need. Can I call any R function using this
interface such as the tests in ctest package?


Thanks a lot.
