In previous lessons, we’ve noted vectors and matrices consist of data elements of the same class. R will coerce data elements to a single class if we attempt to create a vector or matrix with data elements of differing classes. Lists, on the other hand, can hold data elements of different classes, such as the integer, character, or logical class. In fact, a list can hold most anything in R, including vectors, matrices, and many more! None to my surprise, lists can be created with the list() function:
And if you want to work with lists, purrr is a great package to learn.
