Hi
I am new to rapid miner and I have a problem and I dont know how to do it. I have a data with A,B,C,D,F attributes. A and B are only names which I need to see in the result. I want to build a model which clusters the data based on C,D,F. Well, I first use select attributes node to select C,D,F and then I join it to a k-means node. After getting the clustering results, I want to join back A,B and have a result like A,B,C,D,F,Cluster-Number. How should I do it?

Use the Set Role operator to set the role of the A and B attributes to something like A and B respectively. The k-means algorithm will ignore these but they will appear in the output.
