This is a Maven 3 project of JDistLib (http://jdistlib.sf.net) by Roby Joehanes. The code itself has not been changed.
This program is a manual Java translation of R's distribution library found in src/nmath folder of the source tar ball. The translation took place from February 10, 2012 to February 12, 2012 and was based on R version 2.14.1. The original code was in C, so the translation is relatively straightforward, except in a few routines that are peppered with gotos.
What distributions are included? Virtually all standard distribution included in R. See the home page for details: http://jdistlib.sf.net
