Generating a copy of the Temperature attribute of the Golf data set
The 'Golf' data set is loaded using the Retrieve operator. The Generate Copy operator is applied on it. The attribute name parameter is set to 'Temperature'. The new name parameter is set to 'New Temperature'. Run the process. You will see that an attribute named 'New Temperature' has been added to the 'Golf' data set. The new attribute has the same values as the 'Temperature' attribute. The 'Temperature' attribute remains unchanged.
