It's very nice to do it straight up with the XPtr class.
A variant using Rcpp Modules is offerend byy RcppAnnoy -- also templated.

Excellent. Note that the clone method was required for my use case, but it

Thanks, Iñaki! Your package gave me enough hints to create the following
attempt which seemed to have worked.
#include

I may not have been explicit enough. Everything we do goes that route, it's
just that some of the code accessing it is written for you by Rcpp
Attributes. Th
Thanks, for the solution. I tried what you suggested and it shows "no
matching constructor for initialization of 'Rcpp::XPtr'".
Below here is my attempt:
class Distribution {

class Uniform2 {
public:
Uniform2(T max_,mat D_) :
max(max_), D(D_) {}
~Uniform2()
PS And building on top of my post and what Inaki told you, you can of course
have C++ fancypants __provided the fancypants have something as for example
the operator SEXP() in the Rcpp::Nullable(). In short, whatever you do, it
(ultimately) has to convert to a SEXP or there is no calling from R.
Recall that R offers us a C language interface
SEXP .Call("somename", SEXP a, SEXP b, ...);
which imposes constraints on what you put there. I.e. no C++ fancypants.
You can write yourself a _C_ function interface and pass your desired type as
a string, or enum (i.e. int), or ... and then dis
