Hi

 

I want to convert nominal values into numeric, I tried the dummy coding but a column is generated for each value there is, then I use unique integers and I get like an order number but not what the number actually is, all I want is one column with the numeric values, any ideas?

    Hi,

     

    is this a question related to Radoop. I am just asking because of your other recent question... If yes, then probably "Type Conversion" operator is the one you are looking for.

    If it is Studio, then "Parse Numbers" operator looks promising.

     

    Best,

    Hi @sebastian_gonza,

     

    Have you try to : 

     - set your concerned attributes as numeric in the import configuration wizard (step 4 / 4).

        AND/OR

     - use the Parse Numbers operator on your concerned attributes.

     

    I hope it helps,

     

    Regards,
