[R] Simulate an Overdispersed(extra-variance poisson process)?

[Spencer Jones]

Is there a function in R comparable to rpois that can simulate random
variables from an overdispersed poisson distribution? If there is not a
function any ideas/references on how to program one?

thanks,

Take a look at

  ?rnbinom

or

  library(MASS)
  ?rnegbin
