[R-lang] GIGP - random sample? CDF?

[David Reitter]

I have collocation data that fits the Generalized Inverse Gaussian- 
Poisson distribution quite well (via the ZipfR package).  Now I'd like  
to randomly sample from such a distribution.  Does anyone know how to  
do that?

For starters, I could probably do with an integral-free cumulative  
distribution function for a GIGP, as that would get me 3/4 of the way  
there.

(I can think of some iterative/numerical way, but that wouldn't be  
very elegant - I might as well sample from the corpus data in that  
case.)

Thanks
- David
