Scripting in RapidMiner Part I - Macros

A great Medium article from my former colleague Martin Liebig (Schmitz).

In this article I would like to show how you can access and change RapidMiner variables (called Macros and are always strings). We will opt for a Groovy script. The advantage of Groovy over the other methods is, that you can access RapidMiner’s objects directly. With the other options you transfer data over into their respective data frames, transform them, and pass them back. Groovy is way more direct in this sense. - Via Medium
