R Interface to the PHREEQC Geochemical Modeling Package

This software is in alpha status and has not been released to CRAN.

The USGS currently has a rudimentary and unreleased R interface to the PHREEQC geochemical modeling code. The EnviroR project is seeking to provide a more thorough and maintainable R interface for PHREEQC that can be released under the terms of the GNU GPL.
