[R] interval estimates of bivariate means

[Ondřej Mikula]

Dear R-helpers,
I have a bivariate phenotype to be compared between several groups.
Using 'manova' function I can get point estimates of group means. I
would like to plot these estimates together with their confidence
ellipses, but I do not know, how to get interval estimates of group
means as well. Would you be so kind and give me a hint how to proceed?
Best regards
Ondrej Mikula
