R help - Jan 2005 - How can one get scale for ellipses from plotcorr - like in paper of Duncan MURDOCH

Hello!

I used plotcorr for display of correlation matrix. I understand the meaning 
of ellipses but if you show that nice graph to someone who does not it is 
... So I would like to produce the scale of correlations coefficients from 
-1 to 1 by .1 and display corresponding ellipses. Since this can be used 
mainly with plorcorr I thought it would be nice to have additional option 
in plotcorr() to show the legend of ellipses.

I saw that scale in paper from Duncan MURDOCH on ellipses. I don't have 
paper here to cite it.

Any suggestions?
