In christyray/crthemes: A Standardized ggplot2 Theme for Visualizations

Select from the defined color palettes

Description

This selects hex codes from the palettes defined in the internal pal dataset. The list of available palettes can be previewed with pal_names(). Subsets of colors can be selected with the ncol, colors, or species arguments. Only one selection method can be used in the function call. If no selection method is provided, the function will return the full color palette with color names.

Usage

pal_select(
  palette = "default",
  ncol = NULL,
  colors = NULL,
  species = NULL,
  alpha = 1
)

Arguments

palette	Character vector of length 1 defining the palette to select colors from; use pal_names() to see a list of available palettes, default palette is named "default"

A named character vector with the hex codes of the selected colors. Color names are given for ncol and colors selections, and species names are given for species selection.
