Join example sets with a loop
Dear Rapidminer Community,
I have looked through several posts about loops and joins in the forum already but I haven't found what I am looking for.
What I am trying to do:
I have 7 example sets which can be joined with the "join" operator by an outer-join using "date" as join attribute. Instead of building a process where I join all the example sets manually I would like to do this with a loop. This loop should simply go through the example sets and join them together to one big file, is this possible? I have gone through the accessible loop operators but haven't found a solution because if I put the "join" operator in a loop, the operator of course needs two inputs to join something together.
How do I handle this? Is there an operator which can do this?
