expand_plot()
is a convenience function that expands the scales of a
ggplot, as the large node sizes in a DAG will often get clipped in themes
that don't have DAGs in mind.
Arguments
- expand_x, expand_y
Vector of range expansion constants used to add some padding around the data, to ensure that they are placed some distance away from the axes. Use the convenience function
ggplot2::expansion()
to generate the values for the expand argument.
