Viridis-Magma Palette Function

Source: R/palettes.R

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

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.

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.

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.
