Dears,
I am a newbie to Rcpp. I may have found an off-by-one inconsistency in the
handling of List::erase(iter1,iter2) operation with respect to its
homologous in the STL (which I suppose is intended to mimic). In STL,
iter2 can be the container's .end(); in Rcpp, the same gives an out of
boundary error. (See below)
Thanks for the incredible package. Best
Test case...
#include <Rcpp.h>
#include <iostream>
// [[Rcpp::export]]
SEXP truncateTest() {
BEGIN_RCPP
using namespace std;
Rcpp::List l;
std::vector<int> v;
for (int i=1; i<=10; i++) {
v.push_back(i);
l.push_back(i);
}
v.erase(v.begin()+5,v.end()-1);
l.erase(l.begin()+5,l.end()-1); // ?
cout << "std::vector left with " << v.size() << endl;
cout << "Rcpp::List left with " << l.size() << endl;
END_RCPP
}
/*** R
# library(Rcpp)
# sourceCpp("truncateTest.cpp")
# truncateTest()
# #prints 6 and 5
*/
