viridis_magma_palette: Viridis-Magma Palette Function

In vallenderlab/MicrobiomeR: Analyze Microbiome Data

Description

A function that returns a color palette function based off of the viridis package.

Usage

viridis_magma_palette(viridis_number = 800,
  viridis_range = 300:viridis_number, viridis_rev = TRUE,
  magma_number = 500, magma_range = 50:magma_number,
  magma_rev = FALSE, ...)

Arguments

viridis_number	The total number of colors used to generate the viridis palette. Default: 800
viridis_range	Tne range of colors in the viridis palette to use. Default: 300:viridis_number
viridis_rev	A logical for reversing the viridis palette. Default: TRUE
magma_number	The total number of colors used to generate the magma palette. Default: 500
magma_range	The range of colors in the magma palette to use. Default: 0:magma_number
magma_rev	A logical for reversing the magma palette. Default: FALSE
...	These dots are optionally used as both the magma and viridis function parameters.

Details

The primary purpose of this function is to return a palette-function for generating virdis style color palettes. By taking the viridis::viridis() and the viridis::magma() colors, and manipulating them, this function can help create a unique set of colors that you can distinguish on a busy plot. The hopes of this function is to help improve plots that use more than 20 colors. Use the provided example to view the color palette.

Value

The output of this function is another function (grDevoces::colorRampPalette), which takes a number to generate an interpolated color palette as a character vector.

Examples

## Not run: 
if(interactive()){
 # Use the default values
 > pal_func <- viridis_palette()

 > pal <- pal_func(20)

 # Make a pie plot of the colros.
 > pie(rep(1, length(pal)), col=pal)
 }

## End(Not run)
