pottsgibbs

This function produces one simulation of a square <code>numb</code> by <code>numb</code> grid
from a Potts distribution with four colours and a four neighbour
structure, relying on <code>niter</code> iterations of a standard Gibbs sampler.

Gibbs sampling

Potts model

Allows the reenactment of the R programs used in
the book Bayesian Essentials with R without further programming.
R code being available as well, they can be modified by the user
to conduct one's own simulations.
