Brand new Geochemical Data Toolkit (GCDkit 3.0) – is it worth upgrading and browsing documentation? (Yes!)

The freeware Geochemical Data Toolkit (www.gcdkit.org) is a flexible R-language package designed for handling, recalculation and plotting of whole-rock geochemical data from igneous and metamorphic rocks. The current version, GCDkit 3.0, was released in September 2011 and developed in the brand new R 2.13.0 for Windows. The release addresses some stability issues and improves the appearance of the plots. Apart from several new diagrams and plugins, it brings principal conceptual changes. The first is the internationalization – it introduces dictionaries, serving for the translation of classification diagrams. Czech and French localizations are provided as an example. Moreover, the system enables editing plates of multiple plots, in a manner previously available only for some of the stand-alone plots. Lastly, most of the commands can be invoked in batch mode, thus further speeding up otherwise tedious processing of large data files. Meskimen’s Law: There’s never time to do it right, but there’s always time to do it over.
