There is also the fact that the array is being created ready-sorted :-). I assumed this was an artificially simplified example from real code. Or a learning toy. > This isn't really an Rcpp question, but since you asked, .push_back() > is a great way to slow yourself down. Or add data.reserve(20) [1] after creating the vector. Then push_back() is very quick. BTW, apologies for replying to something off-topic. Perhaps, Noah, Stack Overflow would be a better place for pure-C++ questions? (Any other suggestions anyone?)
