Normal deviate generation - Marsaglia's ziggurat method
Since it is available in the `SuppDists' package, why do we need it in the `base' package? There are perhaps hundreds of useful functions that exist in external packages that are not in `base'. My understanding was that one goal was to keep `base' from getting too bloated. -roger

Hi: I was wondering why Marsaglia's new ziggurat method for generating deviates from the standard normal distribution has not been implemented in the R base package. I know that it is available in SuppDists pacakage of Bob Wheeler, as "rziggurat". According my timing tests, it is about 6 to 7 times faster (on a Pentium 2.4 MHz) machine than the default Inversion method used in R base package. thanks, Ravi.
