one more piece of info on AIC

just one other thing about the AIC issue: there is a line in glm.fit which is the following: aic = aic(y, n, mu, weights, dev) + 2 * rank but I couldn't find the function aic so I couldn't investigate further. It looks suspicious though because it seems to me like it should be aic = -2*likelihood + 2 * rank if anyone could help me find the aic function it's appreciated.
Dear Mark,
The aic() function depends on the family that you are using.
E.g.:
binomial()$aic
gaussian()$aic
