Does Rcpp provide some elegant way to let the R user manage persistent c++ objects that have no R type (e.g. internal handles or sessions of some sort)?
In C, I would use R_MakeExternalPtr to create a ptr SEXP that the user can pass from one R function to another. This also makes it easy to add a finalizer with R_RegisterCFinalizerEx so that the garbage collector will automatically clean up the session/handle whenever user deletes the R object. Most Rcpp examples I have seen use function arguments with standard data types that are automatically mapped to R types. Does Rcpp have any special mechanics for managing external objects (pointers) from R which do not map to a SEXP type? Or do I have to fall back on Rinternals for this? _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
