Returning many things
Functions can only return one value. If you want to return multiple things, then you can store them all in a list.
If users want to have the list items as separate variables, they can assign each list element to its own variable using zeallot's multi-assignment operator, %<-%.
glance(), tidy(), and augment() each take the model object as their only argument.
The Poisson regression model of Snake River visits is available as model. broom and zeallot are loaded.
