Removing Non-Duplicates using RapidMiner

I have a dataset of over 42000 records that has several duplicate and unique values. However, I would like to clean it up and remove ONLY non-duplicate values and leave duplicate records. I know the “remove duplicates” operator removes duplicates but in my case, I want to do the opposite. It’s quite easy to accomplish this task on excel but as you know, excel can’t seamlessly handle the size of my dataset. Is there anyway I can perform this task on RapidMiner?

There is already an output port on the Remove Duplicates operator that provides the duplicate examples, so you can simply use that as the input to your downstream process instead of the exampleset with the duplicates removed.7
