Filled Circle Shape palette (discrete)

This function was deprecated because unicode glyphs used for the circles vary in size, making them unusable for plotting.

Shape palette with circles varying by amount of fill. This uses the set of 3 circle fill values in Lewandowsky and Spence (1989): solid, hollow, half-filled, with two additional fill amounts: three-quarters, and one-quarter.

This palette supports up to five values.

Usage

circlefill_shape_pal()

Value

A palette function. It takes the number of shapes n and returns an integer vector of n shape (pch) codes, and can be used as the palette argument of ggplot2::discrete_scale().
