SuperPlot Colour Palette Selection

This function takes an integer n and a character scheme and returns a character vector of n colours from the specified colour scheme. The function supports four colour schemes from Paul Tol ("tol_bright", "tol_vibrant", "tol_muted", "tol_light", "tol_rainbow") and Color Universal Design ("cud" scheme). If the scheme argument is a vector of colours, the function will return the first n colours from that vector, repeating the vector if it has fewer than n colours. If the scheme argument is not a valid colour scheme or a vector of colours, the function will throw an error. Use of get_sp_colors() is valid too.

Usage

get_sp_colours(n, scheme, order = NULL)

get_sp_colors(n, scheme, order = NULL)

Arguments

n

integer number of colours to return

scheme

character name, colour scheme to use Choose from one of four palettes from Paul Tol ("tol_bright", "tol_vibrant", "tol_muted", "tol_light", "tol_rainbow"), or Color Universal Design ("cud"). Or a vector of colours, e.g. c("#FF0000", "green", "#0000FF").

order

optional ordering of the colours: NULL (default, no change), "reverse", "random" (the order used is printed), or an integer vector that is a permutation of 1:n, e.g. c(2, 1, 3). Note that c(1, 5, 3, 4, 2, 6, 7) works well.

Value

character vector of colours

Examples

get_sp_colours(3, "tol_bright")
#> [1] "#4477AA" "#EE6677" "#228833"
get_sp_colours(3, "tol_bright", order = "reverse")
#> [1] "#228833" "#EE6677" "#4477AA"
get_sp_colors(3, "tol_bright")
#> [1] "#4477AA" "#EE6677" "#228833"
