Hi, I'm looking for a most efficient way to call an R function from C++ in a package. I know there are two functions (`R_forceAndCall` and `Rf_eval`) that can do the "call" part, but both are slow compared to calling the same function in R. I also try to use Rcpp and it is the worse one. Here is my test code: C++ code: ``` // [[Rcpp::export]] SEXP C_test1(SEXP f, SEXP x) { SEXP
