CHANGEDRELATIONS

For a given variable and aggmap object, the CHANGEDRELATIONS function determines if there are any changes in the aggmap and the relations in the aggmap since the last time the variable was aggregated.

Return Value

BOOLEAN.

TRUE when changes have occurred, FALSE when they have not, or NA when the function can not determine if changes have occurred.

Syntax

CHANGEDRELATIONS( variable [ [(partition ...) ] aggmap] )

Arguments

variable

The name of the variable whose aggmap object you want to check for changes.

partition

The name of one or more partitons, separated by commas, whose aggmap you want to check for changes.

aggmap
