[Rcpp-devel] fun(Times) with STL

Many thanks, Doug, I feel so-o-o close, but the revised example does not compile.
I have taken the liberty to condense our discussion a little here.

double* myIterator = std::min_element (TimeQ.begin(), TimeQ.end());

The usual idiom is

double TQmin = *std::min_element(TimeQ.begin(), TimeQ.end());

Sorry. ?I didn't read through to the end of your message. ?If you want
the index of the minimum element you can use

int min_el_ind = *std::min_element(TimeQ.begin(), TimeQ.end()) - TimeQ.begin();

The beauty of iterators is that they have more flexibility than simple
pointers and they also carry more information, so that the difference
between two iterators is the index of an element in an array-like
structure.

Here is the revised example as I have distilled it down and edited (does NOT compile):

src <- '
Rcpp::NumericVector TimeQ(arg1);
Rcpp::IntegerVector show_position(1);
int min_el_ind = *std::min_element(TimeQ.begin(), TimeQ.end()) - TimeQ.begin();
show_position[0] = min_el_ind;
return show_position;
'
?fun <- cxxfunction(signature(arg1="numeric"),src,plugin="Rcpp")
Times<-c(1944.285,2920.969,1720.230,1264.438,3607.507,1720.230,25176.020);
fun_test<- fun(Times)
