ellipse draws mathematical ellipses, I believe
For proper bivariate normal density ellipses (not simply contours), check out:

Also, with Recommended packages 'cluster'
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.
Hi Paul,
take a look at base R's function contour (and the Examples section
of its help page), and follow maybe the hints under "See also".

Dear R friends,
Happy new year to you all. Not quite sure if this is the proper place to
ask about this, so I apologize if it is not, and if it isn´t, maybe you can
point me to the right place.
I would like to know if there is any R package that allows me to produce
density ellipses. Searching th
