Stata shape palette (discrete)

Shape palette based on the symbol palette in Stata used in scheme s2mono. This palette supports up to 10 values.

Usage

stata_shape_pal(unicode = FALSE)

Arguments

unicode

If TRUE, return pch codes derived from Unicode glyphs, which exist for every shape of the palette. They are drawn by the device font, so they render as blank boxes in a font without coverage and at unrelated sizes in most fonts; the font from register_shapes_font() has the shapes of this palette at a common size. If FALSE, return base pch codes, which every font can draw but which exist only for some shapes. The default depends on the palette.

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().

Note

Stata's ten plotting symbols all have a base pch equivalent, so this palette supports ten values on either branch and nothing is dropped: solid and hollow circle, diamond, square and triangle, plus the X and the plus sign.
