[Rcpp-devel] Rcpp::ListOf.size() returns signed int?
Hi Christian, Thanks for catching this. I think this is an oversight -- this should return `R_len_t` as well. Or, when long vector support is implemented, `R_xlen_t` should be used instead (especially since `ListOf<T>` is more-or-less a fancy interface over a `List` object) Just pushed a corresponding change to master on Rcpp: https://github.com/RcppCore/Rcpp/commit/0da625a34269191d1683b2edb537d3537367c681 Thanks, Kevin

Minor implementation question - As a learning exercise, I'm working through g++ warnings. After reading SO posts r.e. int vs size_t, I've set all variables that hold or compare object size information to type std::size_t. This fixes compiler warnings for Vector.size(), which doxygen shows have return type R_len_t. ListOf.size() appears the odd man out, returning int. Is there a reason ListOf.size() returns a (signed) int?
