I am not sure you can. The best (only ?) relevant documentation might be John
Chamber's example of 'Rcpp Classes' (see help(setRcppClass) in R once Rcpp is

And as I recall, he is pretty explicit that you can take a C++ class and
"extend" it for prototyping from the R side, but that you cannot access those
extended parts from C++ as only R sees it.  I think you are hitting a similar
constraint here.

It would be nice if this worked but I am not quite sure that it can.
