I want to return a named list of results from a call using Rcpp but the components of the list are accumulated in stages. At the C++ level i have a templated class that contains several data members that are themselves instances of classes.
What I have been doing is defining methods for each of the subclasses that update the list and return it. The signatures look like Rcpp::List updateList(Rcpp::List&) This particular signature reflects my R background where I would might write something like ans <- updateList(comp3, updateList(comp2, updateList(comp1, list())) However, it occurs to me that it might be unnecessary to return the list in C++ because I am passing a reference to the list so updates will change the original argument. Is this a good idea and does it work as long as I pass by reference? (I'm still a little vague on the distinction between passing a reference and passing a classed object.) _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
