ellipses: Create general elipse perimeter coordinates

In cj-holmes/gglcd:

Description

Parameterised elipse equations. Provide an origin (x and y), minor and major radii, an angle of rotation (measured from positive x to the elipse major axis) and a resolution. The funtion returns a list of the x and y coordinates of the perimeter of the elipse.

Usage

ellipses(x, y, angle, length, width, res = 50)

Arguments

x	Elipse centre x coordinate
y	Elipse centre y coordinate
angle	Angle (degrees) of rotation (measured from positive x to the elipse major axis)
length	Length of major axis
width	Length of minor axis
res	Number of points in elipse perimeter

Value

A dataframe
