Display multiple Cheysson palettes

Creates a visual display of multiple color palettes, useful for comparing palettes or showing all palettes of a certain type.

Usage

show_palettes(palettes = NULL, ncol = 1, cex = 0.8)

Arguments

palettes

Character vector of palette names. If NULL (default), shows all palettes. Can also be a palette type ("sequential", "diverging", "grouped", "category") to show all palettes of that type.

ncol

Number of columns for layout (default 1).

cex

Text size multiplier (default 0.8).

Value

Invisibly returns NULL. The function is called for its side effect of creating a plot.

Examples

# Show all sequential palettes (use ncol > 1 to keep panels legible with
# several palettes; a tall single-column layout can also fail to render
# when captured for the pkgdown reference site)
show_palettes("sequential", ncol = 2)


# Show specific palettes
show_palettes(c("1880_21", "1881_12", "1895_16"))
