Description

Create a window object representing a regular (equal-sided) polygon.

Usage

regularpolygon(n, edge = 1, centre = c(0, 0), ...,
               align = c("bottom", "top", "left", "right", "no"))
hexagon(edge = 1, centre = c(0,0), ...,
        align = c("bottom", "top", "left", "right", "no"))

Value

A window (object of class "owin").

Details

The function regularpolygon creates a regular (equal-sided) polygon with n sides, centred at centre, with sides of equal length edge. The function hexagon is the special case n=6.

The orientation of the polygon is determined by the argument align. If align="no", one vertex of the polygon is placed on the \(x\)-axis. Otherwise, an edge of the polygon is aligned with one side of the frame, specified by the value of align.
