Hi Romain,
first let me thank you for the very fast and informative answer!
I suppose, as SEXP is a pointer, that these attempts reuse the memory allocated
in R, right? Further, I presume, that I proceed in the same way for lists from
R to Rcpp, don't I?
In regard to the initialisation list:
There is no constructor of Matrix tht takes a SlotProxy. You can do it in two
steps perhaps.
SEXP tmp = classS4.slot("M_R") ;
M = tmp ;
Or use a specific cast:
> M((SEXP)classS4.slot("M_R"));
In any case, you should use an initialisation list in your constructor anyway,
something like:

Dear Rcpp-Devels,
I am a little confused right now with the following setting:
I have a C++ class with for example the following header
#include
class FirstClass {
public:
Rcpp::NumericMatrix M;
FirstClass(Rcpp::S4& classS4);
~F
