rcols_as_hex: Convert R's built-in named colours to hex codes

In DesiQuintans/desiderata: Assorted utility functions

Convert R's built-in named colours to hex codes

Description

Convert R's built-in named colours to hex codes

Usage

rcols_as_hex(vec = NULL, distinct = FALSE)

Arguments

vec	(Character) A character vector of R's built-in named colours. If left NULL, the entire contents of grDevices::colours() will be used.
distinct	(Logical) Should only distinct colours be returned? Distinct colours do not share the same (0:255)^3 RGB space, and do not have the same hex code. Defaults to FALSE so that you don't get unexpectedly-short vectors.

Value

A named character vector of hex colours that were converted from R's built-in names. The names are the original R colour names that were provided in vec.
