Hi,
Fasten your seatbelts.
First, the

in R are like uses of Calloc with Rcpp no ? they are possible but if we can
avoid them ...

Please note that this is the "in progress" section of modules, so things
can change.
There are probably open questions. e.g. at the moment you have to deal
with who is responsible for the pointers.

Hi,
Fasten your seatbelts.
First, the problem is definitely object slicing. The best resource I
know about to explain it is a chapter of Scott Meyers "Effective C++".
Robin, I would highly recommend that you get it. Specially considering
that you are willing to get your hands dirty.
Anyway,
oups wrong, suppress my last message.

additional remark : i
Robin,
Section 'Known Shortcomings' in the Rcpp-modules vignette says
\item mulitple inheritance: currently, only simple class structures are
representable via \textsl{Rcpp modules}.
If you want multiple inheritance you may need to let go of modules.
Unless of course Romain has another p
additional remark : if operator SEXP() ; is added to class father,
children1_t, and children2_t the solution with XPtr compiles but gives the
same result as the solution with shared_ptr (i.e. slicing)

I am still working on my vector of a class father with inheritance (polymorphic
subclasses ?). I created an exemple below that works fine but I face the known
problem of "slicing" as named here :
