Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies across models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

Note that the sf package now defines tidy spatial objects and is the recommended approach to spatial data. sp tidiers are likely to be deprecated in the near future in favor of sf::st_as_sf(). Development of sp tidiers has halted in broom.
