[R] How to extrct F value

[=?gb2312?B?w8/QwA==?=]

Hello sir:
Here's the result of repeated measures ANOVA.


$"Error: Within"
          Df Sum Sq Mean Sq F value    Pr(>F)    
t          2 524177  262089  258.24 1.514e-06 ***
Residuals  6   6089    1015                      
---
Signif. codes:  0 `***' 0.001 `**' 0.01 `*' 0.05 `.' 0.1 ` ' 1 


My question is: How to extract the F value only?
If the result is a dataframe,it'll be much better for extracting F value.But it isn't.
I'll perform the ANOVA for many genes and rank the F value.So the only useful item is F value. But how to extract the F value?

Thanks from the bottom of my heart!
