DAGstructure class {cherry} R Documentation

## Class "DAGstructure" for storing the result of the construct method that constructs the DAG.

### Description

The class DAGstructure is the output of a call to construct. It stores the DAG structure that is induced by the given sets.

### Slots

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:

### Examples


# 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)
