[Rcpp-devel] Rcpp and CUDA

You might want to have a look at ROpenCL which I am developing.
I gave a presentation about it on UseR2011. (I still need to find time
to make it CRAN worthy though)
It already allows you to create objects in R and move them to OpenCL
run a kernel and retrieve results.
If it is really CUDA you want, it may help you in writing the bindings to CUDA.

Kind regards,
