...ylogenetic uncertainty taken into account and thereby including 100 potential phylogenetic tree scenarios. I've managed to run models on all of the different trees and performed model averaging to get parameter estimates for the intercept and most of the predictor variable slopes using the *AICcmodavg* package and *APE*, but I seem to get stuck with some of the variables that are also included in a two-way interaction in the model. I can obtain values for the two-way interaction but not for the variables separately. The error I receive is: ?Error in modavg.AICgls(parm = "agefirstbreed&quo...

Is there a function that will allow me to run all model iterations if I specify a full model? I am using information criteria to choose between possible candidate models. I have been writing out all possible model combinations by hand, and I am always worried that I am missing models or have made a mistake somewhere. It is also difficult to alter models if I want to change a term. For example,
