Dear Rolf,
I tryed to follow your advices but the results I am getting seems still
strange to me. See below an example of a matrix:
datamat - matrix(c(2.2, 0.4, 0.4, 2.8), 2, 2)
plot(ellipse(datamat),type='l')
eigenval - eigen(datamat)$values
eigenvect - eigen(datamat)$vectors
eigenscl -

Dear list members,
This might be a silly question but I just can't figure it out. I am using

Thanks a lot Rolf, I knew it would be possible to do it that way but I
was just curious to know if the ellipse package was offering such a
feature. Thanks again for you help!

Well, since the help for ellipse makes no mention of such a
facility it is *highly*
