Re: [R] Normal deviate generation - Marsaglia's ziggurat method

[Roger D. Peng]

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.

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.
