[Rcpp-devel] is std::sort function broken??

[Jonas Rauch]

Hi,
I don't have access to a computer with R atm so I can't try. But the
includes="#include <ctime>, #include <time.h>, #include <algorithm>.
#include <vector>"
looks fishy to me. First of all, note the dot before the last "include"
instead of a comma. Secondly: wouldn't you need something like the below?
includes=c("#include <ctime>","#include <time.h>", "#include <algorithm>",
"#include <vector>")

Sorry if I am completely off here. Like I said, can't try right now...

Regards,
Jonas
