Glyos color and fill scales for ggplot2 — scale

Color and fill scales that use a Glyos colorway palette. The _d variants are for discrete data, the _c variants for continuous data, and scale_colour_glyos() / scale_fill_glyos() choose between the two with the discrete argument. scale_color_* spellings are aliases.

Usage

scale_colour_glyos_d(palette = "standard", reverse = FALSE, ...)

scale_fill_glyos_d(palette = "standard", reverse = FALSE, ...)

scale_colour_glyos_c(palette = "standard", reverse = FALSE, sort = FALSE, ...)

scale_fill_glyos_c(palette = "standard", reverse = FALSE, sort = FALSE, ...)

scale_colour_glyos(
  palette = "standard",
  discrete = TRUE,
  reverse = FALSE,
  sort = FALSE,
  ...
)

scale_fill_glyos(
  palette = "standard",
  discrete = TRUE,
  reverse = FALSE,
  sort = FALSE,
  ...
)

scale_color_glyos_d(palette = "standard", reverse = FALSE, ...)

scale_color_glyos_c(palette = "standard", reverse = FALSE, sort = FALSE, ...)

scale_color_glyos(
  palette = "standard",
  discrete = TRUE,
  reverse = FALSE,
  sort = FALSE,
  ...
)

Arguments

palette: Name of a Glyos colorway. See glyos_palette_names().
reverse: Logical. Reverse the order of colors in the palette?
...: Additional arguments passed on to ggplot2::discrete_scale() (discrete) or ggplot2::scale_colour_gradientn() / ggplot2::scale_fill_gradientn() (continuous).
sort: Logical, continuous scales only. Order the palette from darkest to lightest before building the gradient, so the scale reads as low-to-high. See glyos_find_palettes() for palettes that suit this.
discrete: Logical. If TRUE (default) build a discrete scale, otherwise a continuous gradient scale.

Value

A ggplot2 scale object.

Details

Discrete scales draw the first n colors of the palette, where n is the number of levels in the data. If the data has more levels than the palette has colors, the palette is interpolated with grDevices::colorRampPalette() so that every level still receives a distinct color; expect the result to be less legible than the curated colors.

Examples

library(ggplot2)

ggplot(mpg, aes(displ, hwy, color = class)) +
  geom_point(size = 3) +
  scale_colour_glyos("glyaxia")


ggplot(diamonds, aes(cut, fill = clarity)) +
  geom_bar() +
  scale_fill_glyos_d("gatekeeper")


ggplot(faithfuld, aes(waiting, eruptions, fill = density)) +
  geom_tile() +
  scale_fill_glyos_c("spectre")
