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:

summary(rt.aov)

Error: pbn
           Df Sum Sq Mean Sq F value Pr(>F)
Residuals  9 378283   42031

Error: pbn:expCond
           Df Sum Sq Mean Sq F value Pr(>F)
expCond    2   7312  3656.0  0.4663 0.6347
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)"]
