%description
Model fitting, sampling and visualization for the (Hidden) Markov Random
Field model with pairwise interactions and general interaction structure
from Freguglia, Garcia & Bicas (2020) <doi:10.1002/env.2613>, which has
many popular models used in 2-dimensional lattices as particular cases,
like the Ising Model and Potts Model. A complete manuscript describing the
package is available in Freguglia & Garcia (2022)
<doi:10.18637/jss.v101.i08>.
