scale_pru: Discrete color & fill scales based on the PRU palette

In euctrl-pru/ectrlplot: Making ggplot2 graphics in PRU style

Discrete color & fill scales based on the PRU palette

Description

See pru_pal.

Usage

scale_colour_pru(...)

scale_color_pru(...)

scale_fill_pru(...)

Arguments

...

Arguments passed on to ggplot2::discrete_scale aesthetics The names of the aesthetics that this scale works with scale_name The name of the 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. 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 computed by the transformation object A character vector of breaks A function that takes the limits as input and returns breaks as output 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) A function that takes the breaks as input and returns labels as output limits A character vector that defines possible values of the scale and their order. 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 value aesthetic value should missing 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 info. super The super class to use for the constructed scale

Examples

library(ggplot2)
library(scales)

g <- ggplot(mpg[1:48,], aes(displ, hwy, colour = class)) +
    geom_point()
g + scale_color_pru()

p <- ggplot(mpg[1:108,], aes(class)) +
    geom_bar(aes(fill = manufacturer))
p + scale_fill_pru()
