Hi

Happy to contact you again. I would like to convert one column which has 1 or 0(numirical) into nominal ie. active or inactive. it is possible ? is there any node for this ?

You can use the "Rename" node and change the type of the column to StringValue (without actually renaming it).

Hi

rename node changes only Column ID, Not replacing Active for 1 and inactive for 0.

What about the Binner?

Binner is the way I would do it.

Column->Convert & Replace->Number (Integer) to string node and then  string replacer node , again in column nodes.

How about a simple java snipet, perhaps performance is not great though?

return $columnName$==0?"active":"inactive";

Use the option to rename the column and set the return type="string"
