R help - Jun 2004 - extracting p-value of aov F-statistic

Hi, 

I would like to extract the p-value of the F-statistic of a aov-object's
summary. 

Getting the p-value is so easy with t-tests (t.test(g1, y = g2,
var.equal = FALSE)$p.value), but I couldn't find anything like that for
ANOVAs.

Any help appreciated, 

Sven

Maybe something like:

 >?summary.aov

will give you a clue

Look at

str(summary(aov.object))

For example

example(aov)
str(summary(npk.aov))
