Column Length of Independent Variables

When you create a new independent variable (its expression includes functions or constants, but no variable names), the transform that appears in the list automatically includes a colon and number of rows. For example, if your dataset currently has 5943 rows, and you type

It will appear in the transform list as

The default number of rows is the length of the dataset at the time the transform was created. If you wish to specify a different length, you can do so either when you create the transform:

or you can modify the transform after it has been created. If you modify the transform and remove the length completely, the default length will automatically be put back in.
