[R] How do I compare 47 GLM models with 1 to 5 interactions and unique combinations?

[Bert Gunter]

Simple question. 8 million pages in the statistical literature of
answers. What, indeed, is the secret to life?

Post on a statistical help list (e.g. stats.stackexchange.com). This
has almost nothing to do with R. Be prepared for an onslaught of often
conflicting "wisdom."
