UKRI Blues Colour Scales (Discrete)

Source: R/ggplot_colour_discrete.R
scale_colour_ukri_d.Rd

A layer that can be added to ggplot2 plots to change the colour aesthetic to interpolate values from the blues used in the UKRI logo.

Usage

scale_colour_ukri_d(
  colours = "blue",
  aesthetics = "colour",
  scale_name = "UKRI_Blues",
  palette = ukri_blues_palette_func_gen(),
  name = ggplot2::waiver(),
  breaks = ggplot2::waiver(),
  labels = ggplot2::waiver(),
  limits = NULL,
  expand = ggplot2::waiver(),
  na.translate = TRUE,
  na.value = cruk_grey(),
  drop = TRUE,
  guide = "legend",
  position = "left",
  super = ggplot2::ScaleDiscrete
)

Arguments

colours

The colour palette to use for the colours of the plot. By default this is the blues from the UKRI logo. Setting this to "purple" will switch this to the UKRI purples.

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.

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

Passed to ggplot2::discrete_scale().

labels

Passed to ggplot2::discrete_scale().

limits

Passed to ggplot2::discrete_scale().

expand

Passed to ggplot2::discrete_scale().

na.translate

Setting to FALSE will remove NA values from the colour theme.

na.value

The colour of NA values

drop

Should unused factor levels be omitted from the scale?

guide

A function used to create a guide or its name.

position

The position of the scale.

super

The super class to use for the constructed scale.

Value

A layer that can be added to a ggplot2 object.
