Hi,
Here is a small example:
library("Rcpp")
library("inline")
fun <-cxxfunction(,
'
Environment e = Environment::global_env();
NumericVector bar = e["foo"];
bar = bar + 1;
return wrap(bar);
',plugin="Rcpp")
foo <- 1:10
fun()
This function works fine on my windows netbook, but does not work on my
supervisors mac. His computers specs are:
