Fill Data Gaps

iason

I am trying to figure out how to use "Fill Data Gaps".
I am entering data in the form of
1,5
3,15
7,35
8,40

and expect to get something like
1,5
2,?
3,15
4,?
5,?
6,?
7,35
8,40

Instead, I get an error.

com.rapidminer.example.set.SortedExampleSet cannot be cast to com.rapidminer.operator.Model

The process is as simple as that. One "Read CSV" reading the above values, integer id for first column, real attribute for second.

It looks like you are passing the filtered dataset into another operator which expects a model as input. please try to remove all other operators from your process and connect the output of Fill Data Gaps to the process output. That way you can test if the error is from that operator or from one of the later operators.

If you still have problems, please post your whole process setup (go to the xml view of the process and copy the text into this forum, using the "add code" button above).
