Hello,
I tried following code for copying data from an R array to C++ array
variable
------------------------------------------------------------------
#include <R.h>
#include <R_ext/Applic.h>
#include <Rinternals.h>
#include <RInside.h>
int main(int argc, char *argv[])
{
RInside R(argc, argv);
float sum[50];//int sum[50];
R.parseEvalQ("arr<-c(1:50)") ;
for(int i=0;i<=50;i++)
sum[i] = R["arr[i]"];
for(int i=0;i<=50;i++)
std::cout << "value: " << sum[i] << std::endl ;
exit(0);
}
-------------------------------------------------------------------------------
It got compiled and I got following error while running. Error is same for
sum[] to be int/float
terminate called after throwing an instance of 'Rcpp::not_compatible'
what(): expecting a single value
Aborted
