Plot Color Scheme

• plot() allows to quickly display a color scheme returned by colour().

• plot_scheme() shows colors in a plot.

• plot_map() and plot_tiles() produce a diagnostic map for a given color scheme.

• plot_scheme_colorblind() shows colors in a plot with different types of simulated color blindness.

Usage

# S3 method for colour_scheme
plot(x, ...)

plot_scheme(x, colours = FALSE, names = FALSE, size = 1)

plot_map(x)

plot_tiles(x, n = 512)

plot_scheme_colourblind(x)

plot_scheme_colorblind(x)

Arguments

x

A character vector of colors.

...

Currently not used.

colours

A logical scalar: should the hexadecimal representation of the colors be displayed?

names

A logical scalar: should the name of the colors be displayed?

size

A numeric value giving the amount by which plotting text should be magnified relative to the default. Works the same as cex parameter of graphics::par().

n

An integer specifying the size of the grid (defaults to \(512\)).
