Generate color palette

Source: R/PlottingUtils.R
permuteDEpalette.Rd

Generate a color palette. For discrete palettes, hex values are standard up to n = 100, but for larger values of n, they are generated using Polychrome::createPalette().

Usage

permuteDEpalette(type = "discrete", n = NULL, palette = NULL, swatch = FALSE)

Arguments

type

A character string indicating the palette type. Permitted values are "discrete" and "gradient". Defaults to discrete.

n

Number of colors. Default = NULL will return all of the pre-set colors in the palette.

palette

A character string indicating the palette name. Permitted values are "choir", "archr", "inferno", and "frozen". Default = NULL will use "choir" for discrete colors and "inferno" for gradient colors. Alternately, provide a vector of color values to use as starting values for the color palette.

swatch

A Boolean value indicating whether to plot a swatch of the palette.

Value

Returns a vector of n hex values.

Details

The "choir" palette is adapted from function CHOIR::CHOIRpalette in R package CHOIR (Sant et al. 2025). The "archr" palette is adapted from palette "stallion" in R package ArchR (Granja & Corces et al. 2020).
