Stack Variables

This node stacks the input datasource using the stacking variables specified. The following example illustrates the stacking process:

 H1 H2 A B C
 1 2 3 5
 6 7 8 9 10

 Stacking this data, selecting variables A, B, and C (setting Omit missing to 'False') would produce:

 H1 H2 Value Code
 1 2 3 A
 1 2 B
 1 2 5 C
 6 7 8 A
 6 7 9 B
 6 7 10 C
