is.acyclic | R Documentation |
This function checks for each node in a DAG whether backtracing arcs leading to it results in an "infinite recursion" error indicating that there actually is a cyclic part in the DAG (which then obviously seems not to be a DAG).
is.acyclic(dag, maxSecs=NA)
dag |
The DAG to be check. |
maxSecs |
maximum time before function aborts; |
A list with two elements.
acyclic
is a boolean indicating whether the DAG is acyclic (=TRUE) or contains a cyclic component (=FALSE).
nodewise
is a vector containing 1 boolean per node in the DAG, TRUE indicating that backtracing from this node does not lead to a cyclic component, FALSE indicating that backtracing from this node leads to a cyclic component.
