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

[Noah Silverman]

Xian,

Your comment is ridiculous.  

You know nothing about my application, size or data, or other transformation on the data.  

I can assure you that using Rcpp speeds up my process by a factor of at least 100.  I don't know how you measure things, but in my world, that is a VERY appropriate use of Rcpp.

To make such a blind statement is ignorant and insulting.
