paths: Show Paths

In dagitty: Graphical Analysis of Structural Causal Models

Description

Returns a list with two compontents: path gives the actual paths, and open shows whether each path is open (d-connected) or closed (d-separated).

Usage

paths(
  x,
  from = exposures(x),
  to = outcomes(x),
  Z = list(),
  limit = 100,
  directed = FALSE
)

Arguments

x	the input graph, a DAG, PDAG, or MAG.
from	name(s) of first variable(s).
to	name(s) of last variable(s).
Z	names of variables to condition on for determining open paths.
limit	maximum amount of paths to show. In general, the number of paths grows exponentially with the number of variables in the graph, such that path inspection is not useful except for the most simple models.
directed	logical; should only directed (i.e., causal) paths be shown?

Examples

sum( paths(backDoorGraph(getExample("Shrier")))$open ) # Any open Back-Door paths?
