You are looking for XPtr.
https://github.com/RcppCore/Rcpp/blob/master/inst/include/Rcpp/XPtr.h

You can create an external pointer using something like :
XPtr xp( new T(...) )
I think the XPtr class is what you are looking for:

Interesting. If I do
inline SEXP wrap( const arma::vec& x ) {
return wrap(Rcpp::NumericVector( x.begin(), x.end()));
}
then wrap(
I had something simpler in mind. I'll send a pull request when I've
finished testing (This package has many dependencies!)
