From metacoder v0.3.4 by Zachary Foster

Makes coordinates for a regular polygon

Generates an n x 2 matrix containing x and y coordinates between 1 and 0 for the points of a regular polygon.

Keywords: internal

Usage

polygon_coords(n = 5, x = 0, y = 0, radius = 1, angle = 0)

Arguments

n: (numeric of length 1) The number of nodes in the polygon.
x: (numeric of length 1) x coordinate of center
y: (numeric of length 1) y coordinate of center
radius: (numeric of length 1) The diameter of the circle.
angle: (numeric of length 1) Angle to rotate points around the center of the circle.

  geom_polygon(aes(x = x, y = y, fill = group))
