I'd like to automatically plot the p-value and r^2 of a linear model.


I know that I can extract r^2 with 



foo <- lm(y~x)


a <- summary(foo)


a$r.squared



I can't find any similar functionality to obtain the p-value based on


the ftest



a$fstatistic returns the actual f-test and df, but not the p-value.



Any thoughts?



Thanks,



Adam
