Rphree is the R interface to the open source geochemical modelling software PHREEQC. It provides PHREEQC (v 2.17), compiled as shared library, and a set of R utility functions to manipulate PHREEQC scripts, run simulations and visualize the results.
Here is the current build of the package, while here you can find a simple usage example script.
Expect improved examples and tutorials/vignette in the near future. Any contributions in this matter are welcomed!
Consider signing up to the mailing list rphree-general for questions and discussions. This is currently the only mailing list concerning all aspects of development.
