Presenting results from an arbitrary number of models

The combination of tidyr::nest() and purrr:map() can be used to easily fit the same model to different subsets of a single dataframe. There are many tutorials available to help guide you through this process. There are substantially fewer (none I’ve been able to find) that show you how to use these two functions to fit the same model to different features from your dataframe.
