Arguments

x, y

centre coordinates.

radius

circumradius.

nVertices

Examples

canvas(xlim = c(-2, 2))

# a hexagon is the default
polygonX(regPolygon(radius = 1.8), col = "lightblue")

# a square, once standing on a vertex and once on an edge
polygonX(regPolygon(radius = 1.2, nVertices = 4), border = "red")
polygonX(regPolygon(radius = 1.2, nVertices = 4, startAngle = pi/4))

# a triangle pointing upwards
polygonX(regPolygon(radius = 0.5, nVertices = 3, startAngle = pi/2),
         col = "royalblue")
