scale_adjusted() is a convenience function that implements ways of
visualizing adjustment for a variable. By convention, a square shape is used
to indicate adjustment and a circle when not adjusted. Arrows out of adjusted
variables are often eliminated or de-emphasized, and scale_adjusted() uses
a lower alpha for these arrows. When adjusting a collider, a dashed line is
sometimes used to demarcate opened pathways, and scale_adjusted() does this
whenever geom_dag_collider_edges() is used. scale_dag() is deprecated in
favor of scale_adjusted().
Usage
scale_adjusted(
include_linetype = TRUE,
include_shape = TRUE,
include_color = TRUE,
include_alpha = FALSE
)
scale_dag(breaks = ggplot2::waiver())Arguments
- include_linetype
Logical. Include linetype scale for dashed lines on collider edges? Default is TRUE.
- include_shape
Logical. Include shape scale for adjustment status (squares for adjusted, circles for unadjusted)? Default is TRUE.
- include_color
Logical. Include color scale for adjustment status? Default is TRUE.
- include_alpha
Logical. Include alpha scales for de-emphasizing edges from adjusted variables? Default is FALSE.
- breaks
One of:
NULL for no breaks
waiver() for the default breaks computed by the transformation object
A numeric vector of positions
A function that takes the limits as input and returns breaks as output
