R help - Apr 2007 - Random Number Generator of Park and Miller

Hi,

I failed to search for R package providing random number generator of "Park
and Miller". 
Anyone know any R package supporting this kind of function?

Thanks,
Grace

I failed too.
However, here is the source code http://www.firstpr.com.au/dsp/rand31/
which can be either easily rewritten to R or compiled to the shared library,
providing functions, callable from R

By the way, AFAIK, R uses the Mersenne-Twister random number generator, which
"has a much better reputation for producing numbers than any linear
congruential PRNG" (the same url, http://www.firstpr.com.au/dsp/rand31/)

rng.lcg<-function(x,p1=16807,p2=0,N=2147483647){(x*p1+p2)%%N}
