Function Documentation

unifperm()

void oacpp::rutils::unifperm	(	std::vector< int > &	pi,
		int	q,
		RUnif &	randomClass
	)

In S one just does rank(runif(q)). Here we want something like rank(runif(q))-1 since the symbols to be permuted are 0..q-1

Parameters

pi	a vector of integers to be permuted
q	length of the vector
randomClass	a random number generator class
