I would love to make a response vs. covariate figure analogous to Pinheiro and Bates (2000) Fig. 4.12 of lme model predicted values augmented with data, but instead of plotting these by specified random groups, I would like to plot them by fixed factors. Any ideas? Many thanks, Hank Stevens Martin Henry H.
