Let user select response via flow variable

[ArminFan]

Hello,

I’m currently working on a workflow which should let a user test different models on different responses and predictors. The user should be able to select a response and the predictors and then train a random forest and get the results. For me the problem is now, that I cannot let the user select the response (target column) via a flow variable. I can only use the columns provided in the table. Does anyone has some kind of solution for that issue?

Hi @ArminFan,

to my understanding you should use Column Selection Configuration or Column Selection Widget to allow user to choose column from table that will be tagret column. In Random Forest Learner node you then need to go to Flow variables tab and control tagretColumn value with flow variable created from one of above mentioned node.

Hope this helps!

Thanks ipazin, that worked fine. But instead I used the Column Filter widget.
