Set gnomeR color palette — set_gnomer

This function sets the gnomeR color palette as the default palette for all ggplot2 objects. It does so by overriding the following four functions from the ggplot2 package: scale_color_discrete(), scale_fill_discrete(), scale_color_continuous(), and scale_fill_continuous(), and places them in the specified environment. A typical workflow would include this function at the top of a script, and subsequent calls to ggplot() will utilize the gnomeR color palette.

Usage

set_gnomer_palette(
  palette = c("pancan", "main", "sunset"),
  gradient = c("pancan", "main", "sunset"),
  reverse = FALSE,
  env = rlang::caller_env()
)

Arguments

palette: name of palette in gnomer_palettes, supplied in quotes. Options include "pancan", "main", "sunset". Default is "pancan".
gradient: name of gradient palette in gnomer_palettes, supplied in quotes. Options include "pancan", "main", "sunset". Default is "pancan".
reverse: if set to TRUE, will reverse the order of the color palette
env: environment in which palette will take effect. Default is rlang::caller_env().
