How to get from a txt-file with short names and labels to a QGIS-Style (qml-file)?
I used the below R-script to create a style for this legend table where I copy-pasted the parts I needed to a txt-file, like for the WRB-FULL (WRB-FULL: Full soil code of the STU from the World Reference Base for Soil Resources). The vector data to which I applied the style is freely available at ESDAC - you just need to submit a form to get access to the data. BTW, thanks to a helping hand on SO.
You can find the QGIS-styler script in theBioBucket-Repository on GitHub.
