Get a Cheysson color palette — cheysson

Returns colors from a specified Cheysson palette. Palettes can be referenced by name (e.g., "1880_21") or by selecting a palette of a particular type.

Usage

cheysson_pal(palette = "1880_21", n = NULL, type = 1)

Arguments

palette: Name of palette (e.g., "1880_21"), or palette type ("sequential", "diverging", "grouped", "category"). If a type is specified, the first palette of that type is returned.
n: Number of colors to return. If NULL, returns all colors in the palette. If n is smaller than the palette, sequential and diverging palettes return colors spread over the whole palette, keeping both ends; other types return the first n. If n is greater than the number of colors in the palette, colors will be interpolated.
type: If palette is a type name, optionally specify which palette of that type to use (default is 1 for the first).

Value

A character vector of hex color codes
