Hi @m_keshavarz_com

 

You should use GENERATE ATTRIBUTES operator for this. Using this operator, you may create new columns with values based on other columns for each example.

You could also use Generate Aggregation depending on what exactly you want to do in that additional column.  Sometimes that is more efficient than Generate Attributes.  You should look at the tutorial processes for both to understand the differences.

Hi there @m_keshavarz_com, 

 

I'd check out some of our tutorial processes that cover these topics. This will give you a good foundation of RapidMiner. 

Here is the playlist. You can also find them on the website under "Training Videos."

 

Best,
