Plug-in modules

The GCDkit is easily expandable by the so-called Plugins, e.g. text files with R code stored in the subdirectory Plugin. These are all automatically executed (sourced) upon loading the new data set and typically define additional functions, accessible via newly appended menu items.

User-defined modules  

User-contributed plugins are highly appreciated. If you intend to write a plugin, follow several simple rules:

If your function is of wider interest, please share it with other colleagues, as much as we do results of our efforts. We would like to distribute the user-defined plugins on this page, so let us know!

Standard modules

These come with the standard distribution of GCDkit. No extra installation is necessary, including required libraries, distributed within the GCDkit install file.

JungAlTitemp.r

This function estimates the temperature of a granitic magma based on measured Al2O3/TiO2 ratio and experimental constraints. The regression formulae were defined by Jung & Pfander (2007).
