List columns are a powerful way to extend data frames to contain arbitrary data types: you’ve seen them with spatial data, and you’ll find them useful when you start working with many models.
Data frames are useful because they keep together related vectors; list-columns allow you to continue to use data frames even as you data structures get more complicated.
