Solved! Thanx to Vincent Calcagno: /Dear Machteld, In the coming 2.0 version of glmulti, there will be a more proper way to force variables in. In the current version, it has to be done ad-hoc, and you did it well. The 'formulas' only show terms that are shuffled by glmulti; the constant terms are

Re: [R] A panel of contour plots through a iteration process

I would rather use facet_wrap() instead of multiplot() Just combine all your data in one data.frame and make sure that you have a variable indication the iteration. library(reshape2) volcano3d <- melt(volcano) names(volcano3d) = c("x", "y", "z") volcano3d <- merge(volcano3d, data.frame(Iteration

Re: [R] A panel of contour plots through a iteration process

Hi Loukia, I think the problem stems from the fact that the filled.contour "uses the layout function and so is restricted to a full page display" as its documentation reads. And if you look at the documentation of the layout function, it says that it is "totally incompatible with the other mech
