This identifies those nodes in a DAG that are ancestors of the nodes specified, i.e. acc. to the model depicted by the DAG they causally precede those nodes.
 Internally called by <code>dag.adjustment</code> in the context of finding associations introduced by adjustment.

Draw, manipulate, and evaluate directed
