As I am writing this post my 2-year-old toddler who has done many of the movement lessons I. Looking at shapes visually, handling them physically, talking about them and moving their bodies to create them. If we think of 14 as a square with a chevron on top, we can have the convention that the closed shape always comes first (incidentally the orientation of the triangle comes out differently when I plot it from how it is in ?pch - different OS? different R version? Anyway, chevron works both ways).Ħ: open triangle down ġ6: small circle ĭf_shapes Use "plus" and "cross" vs "cross" and "x-mark": "plus" is unambiguous, "cross" can imply different shapes, but is often used for an x mark and works better for combinations of shapes.However, I like your suggestion to have some defaults to avoid long names - as well the default being a solid shape, I suggest assuming triangles are point up unless otherwise stated. describe fill first, use same names for shapes. Find out how to use them in sentences and applications, and see pictures and examples of two-dimensional and three-dimensional shapes. Aim for consistency with the naming in ?pch, i.e. Learn the names of different types of shapes in English, such as circles, triangles, polygons, and more. A list of different geometric shapes to help you identify 2d and 3d shapes, with their properties and images. I was looking into the different shapes that can be passed into, say, geompoint() and I found this old closed GH issue discussing about the ability of using names of shapes instead of a numeric value from 0 to 25.As the names will be specified as character strings, you may as well allow spaces for readability - otherwise perhaps use snake_case for general consistency with ggplot2 conventions.I have a few suggestions for improvements:
