Hi,
I'm writing a R package by Rcpp and I have a problem when setting default value when call a R function in Rcpp. Here is an example to pass a R function to C++, provided by http://adv-r.had.co.nz/Rcpp.html #include <Rcpp.h>using namespace Rcpp;// [[Rcpp::export]]RObject callWithOne(Function f) { return f(1);} The question is, how to set the default value for f? I would like to have the choice to pass a function or not, like callWithOne(Function f = NULL) { // if pass f, run f(1) // else, run something else} Thanks! Best, Jingyu He
