...-Mixed-Models for this one (https://stat.ethz.ch/pipermail/r-sig-mixed-models/2010q3/004170.html), but I think that the final steps to a solution aren't mixed-model specific, so I thought I'd ask my final questions here. I used gamm4 to fit a generalized additive mixed model to data from a AxBxC design, where A is a random effect (human participants in an experiment), B is a 2-level factor predictor variable, and C is a continuous variable that is likely non-linear. I tell gamm4 to fit a smooth across C to each level of B independently, and I can use predict.gam(...,se.fit=T) to obtain pre...
