R help - Oct 2004 - extraction of p-value

R-help,

I wish to get the p-values of anova model as numeric and not as part of
the standard output (print,summary,,,)

I have tried several commands but to not vail

Thank you

Hi

str(summary(fit)) will give you a whole picture how summary 
output list is structured.

summary(fit)[n] 

where n is an appropriate number will extract parts of a list. Just 
try and choose the one you need. Maybe n=4?

Cheers
Petr

It is part of the standard output of summary.

Please do as the posting guide asks and do your homework.  We have no idea 
what you tried and why it `not vail'.

If `anova model' means `aov model', see ?summary.aov.  Continuing that 
example

summary(npk.aov)[[1]]["Pr(>F)"]

something you will find discussed in the R-help archives.
