[R] AIC bug?

[Jean Lejeune]

Dear all,

I am a little problem. In the help, AIC = - 2log L + k*edf. When the model
is linear, the help said " -2log L is the deviance ". I have a model
toto.lm  with one output and three input where 
deviance(toto.lm) = 8.027 and edf =4. But AIC = -31.55. I don't understand
why?
Many thanks.
