stem discrete colour and fill scales for ggplot2

Source: R/color-palettes.R
scale_colour_stem.Rd

Discrete ggplot2 scales that apply a stem colour palette to the colour or fill aesthetic. Three aliases are provided:

  • scale_colour_stem() — maps to the colour aesthetic (British spelling).

  • scale_color_stem() — alias for scale_colour_stem() (American spelling).

  • scale_fill_stem() — maps to the fill aesthetic.

All functions delegate to ggplot2::discrete_scale() via stem_palette_gen(), so any argument accepted by discrete_scale() (e.g. name, breaks, labels, na.value, drop) can be passed through ....

Usage

scale_fill_stem(palette = "div1", direction = 1, ...)

scale_colour_stem(palette = "div1", direction = 1, ...)

scale_color_stem(palette = "div1", direction = 1, ...)

Arguments

palette

Name of the palette. See stem_palette() for the full list of valid names. Defaults to "div1".

direction

1 (default) uses colours in their natural order; -1 reverses the order.

...

Additional arguments passed to ggplot2::discrete_scale().

Value

A ggplot2 Scale object to be added to a plot with +.
