Hi, I am developing a package where I would like to combine two Rcpp Attribute features: * Automatically providing a C++ interface * Renaming the exported function in R to contain a dot
My current attempts at doing so result in a run-time error. Steps to reproduce: * create an new package with Rcpp::Rcpp.package.skeleton() * change src/rcpp_hello_world.cpp to rename the exported function and create both R and C++ interfaces: // [[Rcpp::interfaces(r, cpp)]] #include <Rcpp.h> using namespace Rcpp; // [[Rcpp::export(hello.world)]] List rcpp_hello_world() { CharacterVector x = CharacterVector::create( "foo", "bar" ) ; NumericVector y = NumericVector::create( 0.0, 1.0 ) ; List z = List::create( x, y ) ; return z ; } * build and install the package * reference the function from C++: // [[Rcpp::depends(anRpackage)]] #include <Rcpp.h> #include <anRpackage.h> // [[Rcpp::export]] Rcpp::List wrapper() { return anRpackage::hello_world(); } /*** R wrapper() */ If I rename the function to 'hello_world', this compiles and runs fine. If I rename the function to 'hello.world', it still compiles but fails to run: > wrapper() Error in wrapper() : Function not exported: C++ function with signature 'List(*hello_world)()' not found in anRpackage. Is there a way to combine these two features?
