Dear Sir,

I've got a Rcpp code in the form like the following in my uploaded
package:

inline double runiforminline(){
?? std::default_random_engine generator(rand());
?? std::uniform_real_distribution<double> distribution (0.0, 1.0);
?? return (distribution(generator));
}

But as I uploaded, the system ask me to remove rand(). Various attempt
has
been tried, but all of them result in no randomness at all. Not sure
how to
fix it. Kindly appreciate all helps.

Sincerely,

Chu-Lan Kao ( ??? Michael )
