For a university project in ”Datamining and Datawarehousing”, I have to convert data stored as text files in different formats to the Weka ARFF format.
I did it with Pharo of course! 🙂
So, I wrote this little project  to share what I have done with you, just in case someone else needs to export data from Pharo objects to an ARFF string for further analysis with Weka.
