Hi, I used to get a really useful graph when I ran the following command using the MASS library:
> cov.rob(cbind(dekeyser$AGE,dekeyser$GJTSCORE),cor=T) Besides the regular output, a graph appeared that had the classical correlation and the robust correlation, and two ellipses, one surrounding the data that would be used in the classical correlation and the other surrounding the data in the robust correlation. I've searched through the MASS library but don't see a separate command that could produce this graph. Does anyone know whether one exists, or did the graph just disappear in the newer version of R?
