Modular fitting exercise

• Using either lme4 or glmmTMB, use the modular fitting framework to do a model fit step by step. Use str()/names() (possibly slotNames(), or even DataExplorer::plot_str()?) to explore the structure of the object produced at each step.
  • for lme4, see the steps at ?modular
  • for glmmTMB, see the steps at ?fitTMB
• if you have time, modify something about the structure of the model between steps, or use a wrapper function, and see how it goes.
