Arguments

...: Other arguments passed on to discrete_scale() or continuous_scale() to control name, limits, breaks, labels and so forth
type: One of \"sequential\", \"diverging\" or \"qualitative\"
palette: If a string, will use that named palette. If a number, will index into the list of palettes of appropriate type
direction: Sets the order of colors in the scale. If 1, the default, colors are as output by unhcr_pal(). If -1, the order of colors is reversed
na.value: Missing values will be replaced with this value.
guide: A function used to create a guide or its name. See guides() for more information.
nmax: Maximum number of different colors the palette should contain. If not provided, is calculated automatically from the data.
order: Numeric vector listing the order in which the colors should be used. Default is 1:nmax.

Value

A discrete, continuous or binned Scale object

Examples

library(ggplot2)

data(msleep, package = "ggplot2")

ggplot(msleep, aes(vore, sleep_total, fill = vore)) +
  geom_boxplot() +
  scale_fill_unhcr_d(palette = 1, direction = -1)
