Notes on ZipfR

ZipfR is for Large Number of Rare Events (LNRE) modeling of lexical distributions. So its parameters are named related to the lexicon.

N = sample size.
V = vocabular size.
Number of types (Vm) per frequency class (m).

The question is how to specify gamma for the power-law network model? 
ZipfR limits alpha in ZM model between 0 and 1, this seems to be a major problem for biology network simulation that often have power-law coefficient between 2 and 3. 

ZipfR,  R text package, and igraph probably can be do some interesting projects.
