| rcellnumber {spatstat} | R Documentation |
Generates random integers for the Baddeley-Silverman counterexample.
rcellnumber(n, N = 10)
n |
Number of random integers to be generated. |
N |
Distributional parameter: the largest possible value. An integer greater than 1. |
This function generates random integers which have mean and variance equal to 1, but which do not have a Poisson distribution. The random integers take the values 0, 1 and N with probabilities 1/N, (N-2)/(N-1) and 1/(N(N-1)) respectively. See Baddeley and Silverman (1984).
An integer vector of length n.
