Draws a circle on an existing plot.
draw.circle(x,y,radius,nv=100,border=NULL,col=NA,lty=1,density=NULL,
angle=45,lwd=1)A list with the x and y coordinates of the points on the circumference of the last circle displayed.
Coordinates of the center of the circle.
Radius (or radii) of the circle(s) in user units.
Number of vertices to draw the circle.
Color to use for drawing the circumference.
Color to use for filling the circle.
Line type for the circumference.
Density for patterned fill. See polygon.
Angle of patterned fill. See polygon.
Line width for the circumference.

draw.circle uses the dimensions of the plot and the x and y coordinates to draw a circle rather than an ellipse.
