In malcolmbarrett/ggdag: Analyze and Create Elegant Directed Acyclic Graphs

Activate paths opened by stratifying on a collider

Description

Stratifying on colliders can open biasing pathways between variables. activate_collider_paths activates any such pathways given a variable or set of variables to adjust for and adds them to the tidy_dagitty.

Usage

activate_collider_paths(.tdy_dag, adjust_for, ...)

Arguments

.tdy_dag	input graph, an object of class tidy_dagitty or dagitty
adjust_for	a character vector, the variable(s) to adjust for.
...	additional arguments passed to tidy_dagitty()

Value

a tidy_dagitty with additional rows for collider-activated pathways

Examples

dag <- dagify(m ~ x + y, x ~ y)

collided_dag <- activate_collider_paths(dag, adjust_for = "m")
collided_dag
