[R] Adding axis to an ellipse: "ellipse" package

Dear list members,

This might be a silly question but I just can't figure it out. I am using
the "ellipse" package on covariance matrices. I would simply like to plot my
ellipses WITH its two axis ploted as well. These axis represents the 2 eigen
vectors of my matrix and it is important that I can graphically show them.
Is there an easy way to do so?

Many thanks,
