[R] [R]How to plot a 3D ellipsoid in R?

[Feng Zhang]

Hey, all

I am going to plot several 3-dimensional ellipsoids
in R.
For example, A is such a ellipsoid with
mean u=[1 1 1]', covariance matrix C=[1 0 .5;0 1 .6;.5 .6 1];
So how can I plot such object in 3D space?

Is there some function to achieve this?

Thanks.
