[R] Ranking submodels by AIC (more general question)

[Alexandra Thorn]

Here's a more general question following up on the specific question I
asked earlier:

Can anybody recommend an R command other than mle.aic() (from the wle
package) that will give back a ranked list of submodels?  It seems like
a pretty basic piece of functionality, but the closest I've been able to
find is stepAIC(), which as far as I can tell only gives back the best
submodel, not a ranking of all submodels.

Thanks in advance,
Alexandra
