Description

Returns all parents of the collection (does not necessarily include the input nodes themselves unless they are parents of one another).

Usage

parents(this, nodes, ...)

## S3 method for class 'LatentDigraph'
parents(this, nodes, includeObserved = T, includeLatents = T, ...)

## S3 method for class 'MixedGraph'
parents(this, nodes, ...)

Arguments

this	the graph object.
nodes	nodes the nodes of which to find the parents.
...	ignored.
includeObserved	if TRUE includes observed nodes in the returned set.
includeLatents	if TRUE includes latent nodes in the returned set.
