removing columns from a dataset/analysis
I'm' new to Rapidminer so this is a basic question I'd appreciate your help with.
I'm running a decision tree (ID3Numerical).
How do I:
1) remove columns (variables) from a dataset before processing
2) alternatively, list the subset of the dataset's variables that I want to put through the tree?
In a related issue, how do I store and view a dataset that's been read in without running the whole ETL process again and pausing it after import?!
thanks in advance for all your help.
