Fill scale constructor for OpenIntro IMS colors

Description

Fill scale constructor for OpenIntro IMS colors

Usage

scale_fill_openintro(palette = "main", discrete = TRUE, reverse = FALSE, ...)

Arguments

palette

Character name of palette in openintro_palettes

discrete

Boolean indicating whether color aesthetic is discrete or not

reverse

Boolean indicating whether the palette should be reversed

...

Additional arguments passed to ggplot2::discrete_scale() or ggplot2::scale_fill_gradientn(), used respectively when discrete is TRUE or FALSE

Examples


library(ggplot2)
library(dplyr)

# Categorical variable with two levels
ggplot(evals, aes(x = ethnicity, fill = ethnicity)) +
  geom_bar() +
  scale_fill_openintro("two")

# Categorical variable with three levels
ggplot(evals, aes(x = rank, fill = rank)) +
  geom_bar() +
  scale_fill_openintro("three")

# Continuous variable with levels
# Generates a palette, but may not be the best palette
# in terms of color-blind and grayscale friendliness
ggplot(diamonds, aes(x = clarity, fill = clarity)) +
  geom_bar() +
  scale_fill_openintro()

# For continuous palettes
# use scale_color_gradient instead
ggplot(evals, aes(
  x = bty_avg, y = score,
  color = score
)) +
  geom_jitter(size = 2) +
  scale_color_gradient(low = IMSCOL["blue", "full"], high = IMSCOL["blue", "f6"])

ggplot(evals, aes(
  x = bty_avg, y = score,
  color = cls_perc_eval
)) +
  geom_jitter(size = 2) +
  scale_color_gradient(low = IMSCOL["green", "full"], high = IMSCOL["green", "f6"])
