economist_seq_pal: Economist sequential color palettes

In ggthemes: Extra Themes, Scales and Geoms for 'ggplot2'

Economist sequential color palettes

Description

The Economist's "equal lightness colour scales": six ordered steps for each of the nine hues in the main chart palette, running darkest to lightest. Use them for ordered data, where the main palette is for unordered categories.

Usage

economist_seq_pal(hue = "blue")

economist_gradient_pal(hue = "blue")

Arguments

hue	character. One of "blue", "cyan", "green", "yellow", "olive", "purple", "gold", "gray", or "red".

Details

economist_seq_pal() returns the six steps themselves, for discrete ordered data. economist_gradient_pal() interpolates between them, for continuous data.

Value

economist_seq_pal() returns a palette function that takes the number of colours n and returns the first n of the six hex colours for hue, for use with discrete_scale(). economist_gradient_pal() returns a palette function that takes a numeric vector x of values between 0 and 1 and returns hex colours interpolated between those steps, for use with continuous_scale().
