Description

Detects any colliders given a DAG. node_collider tags colliders and ggdag_collider plots all exogenous variables.

Usage

node_collider(.dag, as_factor = TRUE, ...)

ggdag_collider(
  .tdy_dag,
  ...,
  edge_type = "link_arc",
  node_size = 16,
  text_size = 3.88,
  label_size = text_size,
  text_col = "white",
  label_col = text_col,
  node = TRUE,
  stylized = FALSE,
  text = TRUE,
  use_labels = NULL
)

Arguments

`.dag, .tdy_dag`	input graph, an object of class `tidy_dagitty` or `dagitty`
`as_factor`	treat `collider` variable as factor
`...`	additional arguments passed to `tidy_dagitty()`
`edge_type`	a character vector, the edge geom to use. One of: "link_arc", which accounts for directed and bidirected edges, "link", "arc", or "diagonal"
`node_size`	size of DAG node
`text_size`	size of DAG text
`label_size`	size of label text
`text_col`	color of DAG text
`label_col`	color of label text
`node`	logical. Should nodes be included in the DAG?
`stylized`	logical. Should DAG nodes be stylized? If so, use `geom_dag_nodes` and if not use `geom_dag_point`
`text`	logical. Should text be included in the DAG?
`use_labels`	a string. Variable to use for `geom_dag_repel_label()`. Default is `NULL`.

Value

a tidy_dagitty with a collider column for colliders or a ggplot

Examples

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

node_collider(dag)
ggdag_collider(dag)
