Plot energy palettes

Draws a palette so you can look at it. Given several palette names it draws them as aligned rows instead, one row per palette and one column per entry, which is the quickest way to see how two published colour schemes differ.

Usage

energypal_show(
  palette = NULL,
  n = NULL,
  file = NULL,
  label_style = c("default", "id", "short", "long"),
  include_groups = FALSE,
  include_subtypes = FALSE,
  show_hex = TRUE
)

Arguments

palette

Palette name, or a character vector of names to compare. Defaults to the energypal.palette option, or "carriers". Pass energypal_info()$name to see everything at once.

n

Number of colours to show from each palette. NULL shows all.

file

Path to a palette file, taking precedence over palette. Only meaningful for a single palette.

label_style

How to label entries: "default", "id", "short" or "long". See energypal().

include_groups, include_subtypes

Passed to energypal(); both FALSE by default, matching the plotting palette.

show_hex

Logical; show the hex code alongside the name in the single-palette view (default TRUE).

Value

Invisibly, the palette(s) drawn: a named colour vector for a single palette, or a named list of them.
