Plot a directed acyclic graph.
A `DAG`` object, usually created with the define_model_set()
or DAG()
function.
An optional set of labels to use for the nodes. This should be a named vector, of
the form c(var1 = "label1", var2 = "label2")
.
If left at `NULL``, the variable names of the DAGs are used.
A layout algorithm from igraph, see
ggraph::create_layout()
. By default,
uses the Sugiyama layout algorithm, which is designed to minimize edge crossing in DAGs.
Alternatively, precisely define the layout yourself, by providing a
data.frame
that at least has a column name
with all variable names, and columns x
and y
with positions to be plotted. Setting this parameter overrides algorithm
but other changes,
such as rotation
and flip
s will still be applied.
Size of the node label text.
To avoid the arrows colliding with the nodes, specify the rectangular dimensions of an invisible box around each node. If you have long labels, you need to increase this.
To avoid the arrows colliding with the nodes, specify the rectangular dimensions of an invisible box around each node. If you have multi-line labels, you need to increase this.
Width of the edges.
Curvature of the edges. A slight curvature can look pretty.
Supply the degrees you want to rotate the layout by. This is useful in order to put rotate your upstream nodes towards the top if needed.
Whether to flip the node positions horizontally.
Whether to flip the node positions vertically.
A grid::arrow
object, specifying the shape and size of the arrowheads.
The order of facets is taken from the ordering of the list, with the facet labels coming from the names of the list. If the list is unnamed, sequential lettering is used.
Not used.
