Class "DAGstructure" for storing the result of the construct method that constructs the DAG.
The class DAGstructure is the output of a call to construct. It stores the DAG structure that is induced by the given sets.
These slots are not meant to be directly accessed by the user.
parents:Object of class "list". Stores the parents of each set, indicated by indices.
children:Object of class "list". Stores the children of each set, indicated by indices.
sets:Object of class "list". Stores the sets that are used for the DAG construction.
twoway:Object of class "logical". Is TRUE if the final DAG structure has twoway logical relationships.
(DAGstructure): Indicates whether given DAGstructure has twoway relationships.

# Let us assume we have the following sets that we want to test: sets <- list(c(1,2,3,4), c(1,2), c(2,3,4), c(2,3), 1, 2, 3, 4) # The sets need to have names in order to be able to look up their p-values later names(sets) <- c(1234, 12, 234, 23, 1, 2, 3, 4) # Start by making the corresponding graph structure struct <- construct(sets) # Check whether the DAG has toway logical relations: istwoway(struct)
