Exercise

Plotting pollution in different land uses

You can observe the differences between different continuous-categorical interaction types by visualizing them. Here, you'll look at the different ways the by-type and factor-smooth-type interactions are plotted, an see how the approaches fit the models differently.

Both the models (mod_sep and mod_fs) from the previous exercise are available in your workspace.
