trFrom: Trek reachable nodes.

In SEMID: Identifiability of Linear Structural Equation Models

Trek reachable nodes.

Description

Gets all nodes that are trek reachable from a collection of nodes.

Usage

trFrom(this, nodes, ...)

## S3 method for class 'LatentDigraphFixedOrder'
trFrom(
  this,
  nodes,
  avoidLeftNodes = integer(0),
  avoidRightNodes = integer(0),
  includeObserved = T,
  includeLatents = T,
  ...
)

## S3 method for class 'LatentDigraph'
trFrom(
  this,
  nodes,
  avoidLeftNodes = integer(0),
  avoidRightNodes = integer(0),
  includeObserved = T,
  includeLatents = T,
  ...
)

## S3 method for class 'MixedGraph'
trFrom(
  this,
  nodes,
  avoidLeftNodes = integer(0),
  avoidRightNodes = integer(0),
  ...
)

Arguments

this	the graph object
nodes	the nodes from which to find trek-reachable nodes.
...	ignored.
avoidLeftNodes	a collection of nodes to avoid on the left
avoidRightNodes	a collection of nodes to avoid on the right
includeObserved	if TRUE includes observed nodes in the returned set.
includeLatents	if TRUE includes latent nodes in the returned set.
