Hi Michael,
use: extractAIC to get AIC from an lm object:
y - rnorm(10)
extractAIC(lm(y~1))

You can use AIC to get what you want.
#example from lm help page
ctl - c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
trt - c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
group - gl(2,10,20, labels=c(Ctl,Trt))
weight - c(ctl, trt)
anova(lm.D9 - lm(weight ~
