Supplement 1. An executable FORTRAN program to apply permutation tests and a brief description.

File List pmaxent -- a file containing the executable FORTRAN program Description Pmaxent is an executable FORTRAN program that implements the permutation test described in the original paper. An option appears after starting the program that allows one to learn how the program works and how the input data files must be arranged. The R script, including a compiled FORTRAN subroutine for the maxent solution, is available in the FD library found at install.packages("FD", repos = "http://R-Forge.R-Project.org").
