Define Aesthetics for Directed Acyclic Graphs (DAGs)

aes_dag() is a wrapper around aes() that specifies x, y, xend, and yend, which are required for most DAG visualizations. It merges any additional aesthetics, e.g. color or shape, with the default aesthetic mappings.

Usage

aes_dag(...)

Arguments

...

Additional aesthetic mappings passed as arguments. These can include any aesthetic supported by ggplot2 (e.g., color, size, shape).

Value

A ggplot2 aesthetic mapping object that includes both the default DAG aesthetics and any user-specified aesthetics.

Examples

library(ggplot2)
confounder_triangle() |>
  dag_adjustment_sets() |>
  ggplot(aes_dag(color = .data$adjusted)) +
  geom_dag() +
  facet_wrap(~set)
