You should be able to access the p-value using the $coefficients
variable, which is part of summary.
Try:
results <- summary(lm(speed~dist, cars))
results$coefficients
and then:
results$coefficients[x]
The "coefficients" element of the summary argument is a two
dimensional structure. You might be able to extract a number this way
but choosing the correct number, in this case 8, for the p-value
associated with the dist parameter, might not be so obvious.

where x is the location of particular p-value, or coefficient
supplied, you want, from the results$coefficient vector.
Hope this helps,

Subject: [R] Extract p-value from lm for the whole model
Dear all,
I would like to ask how to extract the p-value for the whole model
from
summary(lm).
This didn't help a lot summary.lm
summary(lm(speed~dist, cars))
Thanks a lot!
