scale_side_mirrored: Side scale for mirrored slabs (ggplot2 scale)

In ggdist: Visualizations of Distributions and Uncertainty

Side scale for mirrored slabs (ggplot2 scale)

Description

This scale creates mirrored slabs for the side aesthetic of the geom_slabinterval() and geom_dotsinterval() family of geoms and stats. It works on discrete variables of two or three levels.

Usage

scale_side_mirrored(start = "topright", ..., aesthetics = "side")

Arguments

start	The side to start from. Can be any valid value of the side aesthetic except "both".
...	Arguments passed on to ggplot2::discrete_scale scale_name The name of the scale that should be used for error messages associated with this scale. palette A palette function that when called with a single integer argument (the number of levels in the scale) returns the values that they should take (e.g., scales::pal_hue()). name The name of the scale. Used as the axis or legend title. If waiver(), the default, the name of the scale is taken from the first mapping used for that aesthetic. If NULL, the legend title will be omitted. breaks One of: NULL for no breaks waiver() for the default breaks (the scale limits) A character vector of breaks A function that takes the limits as input and returns breaks as output. Also accepts rlang lambda function notation. labels One of: NULL for no labels waiver() for the default labels computed by the transformation object A character vector giving labels (must be same length as breaks) An expression vector (must be the same length as breaks). See ?plotmath for details. A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation. limits One of: NULL to use the default scale values A character vector that defines possible values of the scale and their order A function that accepts the existing (automatic) values and returns new ones. Also accepts rlang lambda function notation. expand For position scales, a 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 expansion() to generate the values for the expand argument. The defaults are to expand the scale by 5% on each side for continuous variables, and by 0.6 units on each side for discrete variables. na.translate Unlike continuous scales, discrete scales can easily show missing values, and do so by default. If you want to remove missing values from a discrete scale, specify na.translate = FALSE. na.value If na.translate = TRUE, what aesthetic value should the missing values be displayed as? Does not apply to position scales where NA is always placed at the far right. drop Should unused factor levels be omitted from the scale? The default, TRUE, uses the levels that appear in the data; FALSE uses all the levels in the factor. guide A function used to create a guide or its name. See guides() for more information. position For position scales, The position of the axis. left or right for y axes, top or bottom for x axes. call The call used to construct the scale for reporting messages. super The super class to use for the constructed scale
aesthetics	Names of aesthetics to set scales for.

Value

A ggplot2::Scale representing a scale for the side aesthetic for ggdist geoms. Can be added to a ggplot() object.
