[Rcpp-devel] Getting an R option in Rcpp

[Søren Højsgaard]

Something like

#include <Rcpp.h>
using namespace Rcpp;

// [[Rcpp::export]]
CharacterVector foo() {
  Function opt("getOption");
  CharacterVector x = opt("digits");
  return x;
}

/*** R
foo()
*/

> foo()
[1] "7"

- all though the result is here a character.

Can I access an R option from within an Rcpp function? I'd like the access to happen at runtime, not at compile time. Something like this:

if (getOption("my_option") == x) {
  do this;
} else {
  do that;
}
