empty_dag {simDAG} | R Documentation |
Initialize an empty DAG
object
Description
This function should be used in conjunction with multiple calls to node
or node_td
to create a DAG
object, which can then be used to simulate data using the sim_from_dag
and sim_discrete_time
functions.
Usage
empty_dag()
Details
Note that this function is only used to initialize an empty DAG
object. Actual information about the respective nodes have to be added using the node
function or the node_td
function. The documentation page of that function contains more information on how to correctly do this.

object.
