geom_dag | R Documentation |
geom_dag()
is a helper function that adds common DAG layers to a ggplot.
The purpose of geom_dag()
is to simplify making custom DAGs. Most custom
DAGs need the same basic layers, and so this function greatly reduces typing.
It is not a true geom in that it adds many types of geoms to the plot (by
default, edges, nodes, and text). While the underlying layers, all available
in ggdag, are true geoms, we usually need a consistent set of layers to make
a DAG. geom_dag()
provides this. Because geom_dag()
is not a true geom,
you'll find that it is awkward for sophisticated customization. When you hit
that point, you should use the underlying geoms directly.

size |
A numeric value scaling the size of all elements in the DAG. This allows you to change the scale of the DAG without changing the proportions. |
edge_type |
The type of edge, one of "link_arc", "link", "arc", "diagonal". |
node_size |
The size of the nodes. |
text_size |
The size of the text. |
label_size |
The size of the labels. |
text_col |
The color of the text. |
label_col |
The color of the labels. |
edge_width |
The width of the edges. |
edge_cap |
The size of edge caps (the distance between the arrowheads and the node borders). |
arrow_length |
The length of arrows on edges. |
