It might not hurt to provide a link to your project, if possible.
Non-trivial examples of Rcpp use should be of broad interest here.

I don't see how that hurts.  Do you use any other (external)
libraries, or is it fully self-contained?

Not surprisingly, the "Extensions" manual doesn't fully cover your use-case :)
The Rcpp-modules vignette might help clarify some issues r.e.
integrating C++ libraries with R. Hopefully others can comment more on
your specific memory management questions.

Currently, the project is only used internally at my department and 
still under heavy construction. In particular, I am just about to start 
working on the R-interface. If everything works as expected, however, we 
might work towards publishing the project.

On the contrary, I suppose that should make it easier, since R errors do 
not interfere with C++ exceptions.

The project relies on several mathematical C++ libraries.

Thank you, I will have a look at the vignette.

Dirk's answer is very helpful and actually quite exhaustive.

Best regards,
Peter
