GCDkit 2.3 for R 2.7.0 released on May 11, 2008 

R 2.7.0 released on April 22, 2008

The GeoChemical Data ToolKIT, or in short GCDkit, is a system for handling and recalculation of whole-rock analyses from igneous rocks. It is written in R, a language and environment for statistical computing and graphics. 

Main features of GCDkit are:

• Standard geochemical calculations involving major-, trace-element as well as Sr-Nd data
• Effective data management (searching, grouping)
• Common plots (binary, ternary, spider diagrams)
• Graphic output to publication quality
• Modular architecture (= easily expandable and modifiable)
• Transparent functionality & availability (open source freeware, WWW)

GCDkit version 2.3 was released on May 11, 2008. Read more about its new features

Currently, GCDkit works under the Windows GUI, and Windows2000/NT/XP/Vista are recommended systems. Under previous versions of Windows R may become unstable, failing to redraw graphical windows if too many of them are open. Furthermore, our users reported GCDkit functionality under Linux with emulated Windows.

Download & run instructions:

• Download the R 2.7.0 for Windows from  local archive  on this site or your nearest  mirror.
• To install R, double click 'R-2.7.0-win32.exe'. Select the target installation directory and follow further instructions of the installation wizard.
• Download  GCDkit.
• Double click the downloaded file 'GCDkit2.3_for_R2.7.0.exe' and follow instructions.
• To run GCDkit, double click the GCDkit shortcut and R should start automatically loading GCDkit on the fly.
• Read instructions in menu 'GCDkit | Help' or  documentation

As an alternative for advanced users, GCDkit is also available as a R library. If you prefer this kind of installation, do not forget to install also appropriate versions of 'R2HTML', 'RODBC' and 'sp' libraries from CRAN (All of these are already included in the installation wizard).

As you may imagine, we have invested hours of our time into this free project. Do you like GCDkit? Do you want to support us somehow? Then please link to our page, let us know your comments or submit a bug report. Have you known that you can even contribute some code ? In any case, we would appreciate if you quote the key paper concerned with the GCDkit software:

Enjoy!
