Return positions for equilateral polygon vertices

Return positions for equilateral polygon vertices

pos_polygon(x0 = 0, y0 = 0, n = 5, radius = 1, rotation = -0.5)

Arguments

x0	numeric x center of shape, defaults to 0
y0	numeric y center of shape, defaults to 0
n	number of positions
radius	a numeric value, the distance between x0 and y0 and the vertices
rotation	numeric indicating how much polygon should be turned from first vertex along positive horizontal

Value
