How to invert the example order?
I'm new to Rapid Miner and currently trying to use it on my first data set. I am desperately looking for a way to invert the order of my examples, i.e put the first row last, the second row second-to-last, and so on. The sort-operator refuses to work on the row-number (which kind of makes sense, since this isn't a real attribute). It's quit a big data set, and my current work-arounds take way to much time. Any ideas?
For context: I actually want to do this to remove certain duplicates. The remove duplicates operator seems to keep the first example and delete every duplication afterwards. I would like to keep the last example and remove all duplicates before (I'm filtering on a subset for the remove duplicates opertor). So my idea was to invert the order of examples to achieve this.
Thank you for your help!
