Somehow I ran into following situation:
after applying a model trained with a decision tree in a cross validation the performance result is looking very "strange". Suddenly on the precision and recall view the rows and the columns are changed causing all the values as precision and recall to become (100% - x).
I attach the pictures from the view. This happened with the recent Rapidminer version downloaded from the website on my Macbook Pro with Mac OSX 10.10.1.
