Position scales for discrete data ggside scales

Description

The xside and yside variants of scale_x_discrete/scale_y_discrete. scale_xsidey_discrete enables better control on how the y-axis is rendered on the xside panel and scale_ysidex_discrete enables better control on how the x-axis is rendered on the yside panel.

Arguments

...	Arguments passed on to discrete_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()). 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. 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. 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. 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. aesthetics The names of the aesthetics that this scale works with. scale_name The name of the scale that should be used for error messages associated with this scale. 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. call The call used to construct the scale for reporting messages. super The super class to use for the constructed scale
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.
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.

Value

ggside_scale object inheriting from ggplot2::ScaleDiscretePosition

Examples

library(ggside)
library(ggplot2)
# adding discrete y-scale to the x-side panel, when main panel mapped to continuous data
ggplot(mpg, aes(displ, hwy, colour = class)) +
  geom_point() +
  geom_xsideboxplot(aes(y=class), orientation = "y") +
  theme(ggside.panel.scale = .3) +
  scale_xsidey_discrete(guide = guide_axis(angle = 45))

#If you need to specify the main scale, but need to prevent this from
#affecting the side scale. Simply add the appropriate `scale_*side*_*()` function.
ggplot(mpg, aes(class, displ)) +
  geom_boxplot() +
  geom_ysideboxplot(aes(x = "all"), orientation = "x") +
  scale_x_discrete(guide = guide_axis(angle = 90)) + #rotate the main panel text
  scale_ysidex_discrete() #leave side panel as default
