Details

The plotwidgets package contains a number of predefined palettes, different from those in RColorBrewer.

• default: a standard, relatively safe (see below) palette

• safe: safe for color blind persons, based on Wang B. "Points of view: Color blindeness", Nature Methods 8, 441(2011)

• neon: a bright palette suitable for drawing on dark backgrounds

• pastel: a dimmed pastel palette

• haze: very delicate pastel colors

• dark: same hues as haze, but much darker

• grey: different shades of grey

• alphabet: based on "A colour alphabet..." by Paul Green-Armytage

• few: a palette based on Stephen Few's book

• zeileis: based on Zeileis et al. 2009

• vizi: automatically generated palette

You can get all the names of palettes with names(plotPals()), and showcase them with showPalettes(). Furthermore, you can use the pal parameter to plotwidgetGallery to see how this palette looks like with different plot widgets.

Value

Either a list of palettes, or (if only one palette was selected) a character vector with colors
