[R] extract the p value of F statistics from the lm class

[tedzzx]

Dear R users

I have run an regression and want to extract the p value of the F
statistics, but I can find a way to do that.

x<-summary(lm(log(RV2)~log(IV.m),data=b))

Call:
lm(formula = log(RV2) ~ log(IV.m), data = b[[11]])

Residuals:
     Min       1Q   Median       3Q      Max 
-0.26511 -0.09718 -0.01326  0.11095  0.29777 

Coefficients:
            Estimate Std. Error t value Pr(>|t|)    
(Intercept)  -0.3059     0.1917  -1.595    0.121    
log(IV.m)     0.9038     0.1065   8.488 1.38e-09 ***
---
Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 

Residual standard error: 0.1435 on 31 degrees of freedom
Multiple R-squared: 0.6991,	Adjusted R-squared: 0.6894 
F-statistic: 72.04 on 1 and 31 DF,  p-value: 1.379e-09 

names(x)
 [1] "call"          "terms"         "residuals"    
 [4] "coefficients"  "aliased"       "sigma"        
 [7] "df"            "r.squared"     "adj.r.squared"
[10] "fstatistic"    "cov.unscaled"

x$fstatistic
   value    numdf    dendf 
72.04064  1.00000 31.00000 

But can not find the p value of F statistics. 

Thanks

Ted
