add.node

Conveniently adds a node to an existing DAG, inserting its coordinates and
 label before the outcome node. Also updates the arcs correspondingly.

Draw, manipulate, and evaluate directed
acyclic graphs and simulate corresponding data, as described in International Journal of Epidemiology 50(6):1772-1777.
