Shape scale

Declare the scale for a mapped (discrete) shape aesthetic. Levels cycle through a default set of marker shapes unless values is given. A shape legend is drawn automatically.

Usage

scale_shape(plot, values = NULL, name = NULL)

Arguments

plot

A PlotSpec.

values

Character vector of shapes (each one of "circle", "square", "triangle", "diamond", "plus", "cross"), or NULL for the default.

name

Legend title, or NULL to derive from the encoding.

Value

The modified PlotSpec.

Examples

vplot(mtcars) |> mark_point(x = wt, y = mpg, shape = factor(cyl))
