I forgot to mention that the ellipse has a rotation. It's horizontal
axis is not parallel to the x-axis.
Just repeating, when I try to draw a circuit keeping the center same
as the ellipse, and radius equal to the first value returned by

Jari, thanks for the quick answer.

what will this return?
For my data, I get:
> sqrt(eigen(cov.trob(r)$cov)$values)
[1] 1.857733e-05 4.953181e-06
Is this Left hand value the major or the semi major length?
I also try to plot a circuit keepi

I have a matrix(3000x2) of numbers and I have plotted a scatterplot
(defined in the ``car'' library.)
scatterplot(r$V1,r$V2,ellipse=TRUE)
The ellipse plotted is an error ellipse.
I want the find the major(semi), minor(semi) minor axis length of this
ellipse.
Does anybody know how to do it?
I ca
