dagitty (version 0.3-4)

plot.dagitty: Plot Graph

Description

A simple plot method to quickly visualize a graph. This is intended mainly for simple visualization purposes and not as a full-fledged graph drawing function.

Usage

# S3 method for dagitty
plot(
  x,
  abbreviate.names = FALSE,
  show.coefficients = FALSE,
  adjust.coefficients = NA,
  node.names = NULL,
  ...
)

Arguments

x

the input graph, a DAG, MAG, or PDAG.

abbreviate.names

logical. Whether to abbreviate variable names.

show.coefficients

logical. Whether to plot coefficients defined in the graph syntax on the edges.

adjust.coefficients

numerical. Adjustment for coefficient labels; the distance between the edge labels and the midpoint of the edge can be controlled using this paramer. Can also be a vector of 2 numbers for separate horizontal and vertical adjustment. NA means no adjustment (default).

node.names

If not NULL, a named vector or expression list to rename the nodes.

...

not used.

Details

If node.names is not NULL, it should be a named vector of characters or expressions to use to rename (some of) the nodes, e.g. node "X" could be renamed using expression(X = alpha^2).

Examples

# Showing usage of "node.names"
plot(dagitty('{x[pos="0,0"]}->{y[pos="1,0"]}'), node.names=expression(x = alpha^2, y=gamma^2))
