Behalf Of Patrick B ? dard Sent: January-30-09 6:31 PM To: r-help at r-project.org Subject: [R] Ancova Hello, I have the following ancova: my_ancova = aov(x~a+b) How do I obtain the means of b once the covariate a has been removed?
One way is to use the function effect() in the effects package:
effect("b", my_ancova)
which will give you the adjusted means for x at the levels of b with a set
to its overall mean.
I hope this helps,
John
thanks
