Filter/compare value of current row with the next row.
I have a need to create a filter similar to the one in IBM SPSS. In IBM SPSS there is a function @offset. It compares the current value with the value in the next row or previous row.
More details about @offset are at the following link.
Is it possible to create a similar function in RapidMiner.
Basically what I want to do is:
If (value of column x of current row = to value of column x or y of a differnt row)
then (calculation etc).
