/**
* @class vtkContingencyStatisticsGnuR
* @brief A class for bivariate correlation contigency
* tables, conditional probabilities, and information entropy. The p-value are
* calculated using R.
*
*
* Given a pair of columns of interest, this class provides the
* following functionalities, depending on the operation in which it is executed:
* * Learn: calculate contigency tables and corresponding discrete joint
* probability distribution.
* * Derive: calculate conditional probabilities, information entropies, and
* pointwise mutual information.
* * Assess: given two columns of interest with the same number of entries as
* input in port INPUT_DATA, and a corresponding bivariate probability distribution,
* * Test: calculate Chi-square independence statistic and, if VTK to R interface is available,
* retrieve corresponding p-value for independence testing.
*
* @par Thanks:
* Thanks to Philippe Pebay and David Thompson from Sandia National Laboratories
* for implementing this class.
