Color Palettes

The palette_*() functions generate a vector of n colors for nodes or edges. They are registered under their short names (for example "colorblind"), which sn_palette accepts, and list_palettes() returns the registered names.

palette_rainbow()

Rainbow hues.

palette_colorblind()

The colorblind-safe colors of Wong.

palette_pastel()

Soft pastel colors.

palette_viridis()

The viridis family, chosen by option.

palette_blues(), palette_reds()

Sequential blue or red shades.

palette_diverging()

Blue to red through midpoint.

Usage

list_palettes()

palette_rainbow(n, alpha = 1)

palette_colorblind(n, alpha = 1)

palette_pastel(n, alpha = 1)

palette_viridis(n, alpha = 1, option = "viridis")

palette_blues(n, alpha = 1)

palette_reds(n, alpha = 1)

palette_diverging(n, alpha = 1, midpoint = "white")

Arguments

n

Number of colors to generate.

alpha

Transparency, from 0 (transparent) to 1 (opaque).

option

Viridis option, one of "viridis", "magma", "plasma", "inferno", "cividis". Any other value gives the "viridis" colors.

midpoint

Color of the midpoint of the diverging palette.

Value

The palette_*() functions return a character vector of n colors. list_palettes() returns a character vector of palette names.

Examples

splot(regulation_net, node_fill = palette_colorblind(n = 10))
