[Rcpp-devel] R/C++ post on R Devel Blog

there was a pretty big follow-up discussion on R-devel that's worth reading:

but I want to point out that people may have misunderstood the recommendation - if you just use Rcpp (or other means) to get data from R, run some C++ code and then return results back, it's completely fine and not what the scope of his post was. It was about mixing R API calls and C++ in ways where you intersperse C++ allocations with R API calls and/or where you create classes with R API which is requires a lot more knowledge than people realize.

That said, I think the Rcpp community is the best line forward here, since Rcpp is in a position to clarify the technical issues and provide tools if need be. For example, just flagging Rcpp calls that don't call (non-macro) R API and thus are "safe" could be useful. I think we could use more supportive comments from Rcpp users/developers on that thread ;) - just my $.02.
