Draw Ellipse

Description

Draws multiple ellipses on a plot window.

Usage

profoundDrawEllipse(xcen = 0, ycen = 0, rad = 1, axrat = 1, ang = 0, box = 0, ...)

Arguments

xcen	Numeric vector; x centre/s of the ellipse/s.
ycen	Numeric vector; y centre/s of the ellipse/s.
rad	Numeric vector; the major axis extent of the ellipse/s.
axrat	Numeric vector; the axial ratio of the ellipse/s as given by radlo/radhi.
ang	Numeric vector; the angle of the ellipse/s in the usual ProFit sense, see profitMakeModel.
box	Numeric vector; the boxiness of the ellipse/s in the usual ProFit sense, see profitMakeModel.
...	Further arguments to be passed to lines to draw the ellipse/s.

Details

This function uses all the standard ProFit conventions to define the input parameters

Value
