Makes coordinates for a regular polygon

Description

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

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.

Examples

## Not run: 
library(ggplot2)
ggplot(data = polygon_coords(n = 4:13, x = rnorm(10), y = rnorm(10), radius = .5)) + 
  geom_polygon(aes(x = x, y = y, fill = group))

## End(Not run)
