Setting Options for the Set to Flag Node

Set fields. Lists all data fields with a measurement level of Nominal (set). Select one from the list to display the values in the set. You can choose from these values to create a flag field. Note that data must be fully instantiated using an upstream source or Type node before you can see the available nominal fields (and their values). See the topic Type Node for more information.

Field name extension. Select to enable controls for specifying an extension that will be added as a suffix or prefix to the new flag field. By default, new field names are automatically created by combining the original field name with the field value into a label, such as Fieldname_fieldvalue.

Available set values. Values in the set selected above are displayed here. Select one or more values for which you want to generate flags. For example, if the values in a field called blood_pressure are High, Medium, and Low, you can select High and add it to the list on the right. This will create a field with a flag for records with a value indicating high blood pressure.

Create flag fields. The newly created flag fields are listed here. You can specify options for naming the new field using the field name extension controls.

True value. Specify the true value used by the node when setting a flag. By default, this value is T.

False value. Specify the false value used by the node when setting a flag. By default, this value is F.

Aggregate keys. Select to group records together based on key fields specified below. When Aggregate keys is selected, all flag fields in a group will be "turned on" if any record was set to true. Use the Field Chooser to specify which key fields will be used to aggregate records.
