R help - Nov 2010 - extract p-value from an aov-oject

Hello!

I am trying to extract a p-value from an aov-object. I?ve done some research
on the internet and found a number of solutions, but somehow, none seems to
work for me.

This is the Object:

> Residuals 18 141122  7840.1 
I would like to recieve an object, that only includes "0.6347".

Any Advice?

Try

   summary(rt.aov)[[2]][[1]][1,5]

or

   summary(rt.aov)[[2]][[1]][1,"Pr(>F)"]

Peter Ehlers
