Update R-entropy to version 1.2.0.

             CHANGES IN `entropy' PACKAGE VERSION 1.2.0

* new functions KL.plugin(), KL.empirical(), Kl.Dirichlet(), and 
  KL.shrink() for computing the Kullback-Leibler divergence.
* new functions chi2.plugin(), chi2.empirical(), chi2.Dirichlet(), and
  chi2.shrink() for computing the chi-squared statistic.
* new functions chi2indep.plugin(), chi2indep.empirical(), 
  chi2indep.Dirichlet(), and chi2indep.shrink() for computing the 
  chi-squared statistic of independence.
* new discretize2d() function for simple binning of a pair of random
  variables.
* in all shrinkage functions the target option has been removed (and
  the default uniform target is now always used).
 
             CHANGES IN `entropy' PACKAGE VERSION 1.1.9

* new discretize() function for simple binning of a continuous random
  variable.
* now requires R >= 2.15.1.

             CHANGES IN `entropy' PACKAGE VERSION 1.1.8

* License file removed.
* Dependencies updated.
* the functions freqs.shrink(), entropy.shrink(), mi.shrink(), 
  entropy(), and freqs() now allow to specify the shrinkage intensity.
