Nobody can tell, really, as you posted no code. Please do.

There are over as dozen small, self-contained examples in the RInside sources
that you can use as a starting point.

Also, do not forget that you canot have more than precisely one instance of
RInside in your code due to the way R is organised (single-threaded etc).
