Re: [R] Using the effects package to plot logit probabilities

Dear Abraham, It's not entirely clear to me what you want to plot. If you want the "effect display" for each predictor holding the others to typical values, plot(allEffects(md1)) will do that. But you appear to want to plot fitted probabilities for combinations of the predictors even though the

With multiple predictors, I feel that predict ends up being less elegant. Plus, I've found a lot of the simple log-odds plots available in the effect package to be simple and easy to use as compared to base predict. On Mon, Aug 13, 2012 at 3:01 PM, Bert Gunter wrote: > Why not use > > ?predict.g
