GNU R package for distributions sometimes useful in hydrology

 This package contains several probability distributions that are
 sometimes useful in hydrology, including the three-parameter gamma
 distribution, the generalized Pareto distribution, the generalized
 extreme value distribution, the Gumbel distribution, the kappa
 distribution, the four-parameter kappa distribution, the log-Pearson
 type III distribution, the log-logistic distribution, the
 three-parameter log-logistic distribution, the three-parameter
 lognormal distribution, and the three-parameter Weibull distribution.
