[R] 3D ellipsoid confidence region

[Melanie Edwards]

I am curious if there is code developed to plot confidence regions in 3D.
The scatterplot3d function generates the plot I want, but would like an 3D
equivalent to the data.ellipse function.

Any help in this direction would be appreciated, be it theoretical,
graphical, or otherwise.
