uses modulus 2^30. Therefore there are only 2^30 distinct numbers, which is confirmed by my previous test in R. If someday Knuth's double version is also included in R, it will be great. Shengqiao Li On Fri, 15 Aug 2008, Duncan Murdoch wrote: On 15/08/2008 10:28 AM, Shengqiao Li wrote:

d.edu/~knuth/programs.html instead of the integer versions in R. I'm a R user. So why not also include the double verion in R implementation? Thanks again, ==== Shengqiao Li Research Associate The Department of Statistics PO Box 6330 West Virginia

Professor Ripley, Thank you for your solution. So the last paragraph of the Note in RNG help page will be updated since Wichmann-Hill is different from other supplied uniform generators in the number of distinct values? Shengqiao Li On Fri, 15 Aug 2008, Prof Brian Ripley wrote: Remember

Unfortunately, RNGkind is buggy. It will not generate warnings except the full name "Buggy Kinderman-Ramage" is supplied for normal.kind. match.arg is supposed to be called before "==" comparison. ======== Shengqiao Li Research Associa
