[Rcpp-devel] arma to Rcpp

[Stefano Calza]

Hi everybody

this is probably a trivial question,but still something is not clear to me.

Moving from SEXP => Rcpp => arma objects (say a matrix) I could do:

Rcpp::NumericMatrix A(clone(X)); // I want deep copy
arma::mat B = as< mat >(A); // again a copy

...
some code here that modifies B
...

Now, what shall I do if I want to transform B into a Rcpp::NumericMatrix?
Why? For example I might want to add attributes to it.

wrap() is no good, so what else?

Stefano
