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.

Examples

library(ggplot2)

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