Stacking IOObject output for different models in a simple csv table

Hi @sebastian_gonza,

Can you post your XML process? Yes, it should be doable. Let's see what you've got.

All the best,

Rodrigo.

 Sure, I attach a sample

Thanks

Hi,

the key operator is Append. it can merge a colection of example sets into one, if the schema is the same.

BR,

Martin

In the ending of the loop and after the collection does not work, where should the append be placed?

thanks

Hi,

after the loop. you need to ensure that the data has the same schema though.

BR,

Martin

Sorry, I dont understand the same schema, if you refer to the structure of each IOObject, is a linear regression by Id, some time is calculated others not, I get the error "The operator needs a rapidminer input type which is not provided"

Sorry, is it possible for you to have a look at the last reply please? thanks

Hi @sebastian_gonza - ok I see what's going on here. So it's not a good idea to mix your models with your ExampleSets. It's like apples and oranges, and hence RM has no idea what to do with that (and hence weird error message).

I don't see more than one model in your XML so I'm not sure what you're trying to do there, but this may guide you in a good direction:
