[R] extracting p-value of aov F-statistic

[Chuck Cleland]

Sven:
   A suggestion from Peter Dalgaard in the archives:

http://tolstoy.newcastle.edu.au/R/help/01a/2097.html

data(warpbreaks)

LZ.aov <- summary(aov(breaks ~ wool + tension, data = warpbreaks))

as.matrix(LZ.aov[[1]][,5])
             [,1]
[1,] 0.073613669
[2,] 0.001377778
[3,]          NA

hope this helps,

Chuck Cleland
