base functions create an object of class dagitty; ggdag_* functions are wrappers that also call ggdag() on the dagitty object.

Arguments

x, y, a, b, m, z

Character vector. Optional label. Default is NULL

x_y_associated

Logical. Are x and y associated? Default is FALSE.

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 DAG of class dagitty or a ggplot

Examples

m_bias() %>% ggdag_adjust("m")
ggdag_confounder_triangle()
