[R] How to create density ellipses with R

Dear Paul,

As I understand it, the ellipse package is meant for drawing confidence 
ellipses, not density (i.e., data) ellipses. You should be able to use 
ellipse::ellipse() to draw a bivariate-normal density ellipse (assuming 
that's what you want), but you'll have to do some computation first.

You might find the dataEllipse() function in the car package more 
convenient (again assuming that you want bivariate-normal density contours).

I hope this helps,
