position_dodge_nested: Nested dodge positions

Description

These functions use nested positioning for distributional data, where one of the positions is dodged. This allows you to set different position adjustments for the "main" and "distribution" parts of your plot.

Usage

position_dodge_dodge(
  width = NULL,
  preserve = "single",
  orientation = "x",
  reverse = FALSE
)
position_dodge_identity(
  width = NULL,
  preserve = "single",
  orientation = "x",
  reverse = FALSE
)
position_identity_dodge(
  width = NULL,
  preserve = "single",
  orientation = "x",
  reverse = FALSE
)

Value

A ggplot2 position

Arguments

width

Dodging width, when different to the width of the individual elements. This is useful when you want to align narrow geoms with wider geoms. See the examples.

preserve

Should dodging preserve the "total" width of all elements at a position, or the width of a "single" element?

orientation

Fallback orientation when the layer or the data does not indicate an explicit orientation, like geom_point(). Can be "x" (default) or "y".

reverse

If TRUE, will reverse the default stacking order. This is useful if you're rotating both the plot and legend.

Aesthetics

position_dodge() understands the following aesthetics. Required aesthetics are displayed in bold and defaults are displayed for optional aesthetics:

Examples

library(ggplot2)

# ggplot dodge 
ggplot(mpg, aes(class)) + 
  geom_bar(aes(fill = drv), 
           position = position_dodge(preserve = "single"))
           
# normal dodge without nesting
ggplot(uncertain_mpg, aes(class)) + 
  geom_bar_sample(aes(fill = drv), position = "dodge")
  
# dodge_identity
ggplot(uncertain_mpg, aes(class)) + 
  geom_bar_sample(aes(fill = drv), position = "dodge_identity", alpha=0.2)

# dodge_dodge
ggplot(uncertain_mpg, aes(class)) + 
  geom_bar_sample(aes(fill = drv), position = "dodge_dodge")

# identity_dodge 
ggplot(mpg, aes(class)) + 
  geom_bar(aes(fill = drv), alpha=0.5, position = "identity")
ggplot(uncertain_mpg, aes(class)) + 
  geom_bar_sample(aes(fill = drv), position = "identity_dodge", alpha=0.7)
