Hi,
I have a vector of doubles that I want to sort.
Using Rcpp and inline. When attempting to create the function, I receive an
error. Does anybody have any suggestions?
===================
Test <- cxxfunction(
signature(),
plugin="Rcpp", includes="#include <ctime>, #include <time.h>, #include
<algorithm>. #include <vector>",
body="
std::vector<double> data;
for(int i=0; i != 20; i++){
data.push_back(i);
}
std::sort(data.front(), data.back());
return Rcpp::wrap(data);
"
)
Error in compileCode(f, code, language = language, verbose = verbose) :
Compilation ERROR, function(s)/method(s) not created!
