The spsann package, provider of methods for the optimization of sample configurations using
spatial simulated annealing in R, requires cramer() for some of its functions to
work. The development version of the spsann package is available on
https://github.com/Laboratorio-de-Pedometria/spsann-package.
Details
Any integer variable is internally converted to a factor.
