Hi ppl.
Look what happens when I use JOIN operator to combine to dataset that contains just two examples.
Resulting dataset has 4 examples, instead of two.
Why?
Hi Daniel,
Did you check out this blog post: https://rapidminer.com/tips-tricks-different-ways-to-join-data/ ?
There are different ways to join data in RapidMiner and each has their unique way to do it. If you were using a Join operator and set to Inner Join and you have matched up the attribute (columns) that you want to join in, then only the records that are found in both data sets is returned.

Is it possible to add more than one attachement btw,
or should point to my google drive location maybe?
I have found ¨REMOVE DUPLICATES¨ operator, that can make the job I guess.
Ok Thomas, thanks for those tricks.
Already did the job, using remove duplicates because join was giving me datasets that cointained
more examples that I was expecting.
Thanks a lot.
