Setting names

If you have an unnamed list, you can, of course, name each element. This can be very useful for being able to call out certain elements in a list, regardless of their order, especially if you are working with a list that may grow or change over time, or if you use the same code on several different lists. For instance, if you have a list that contains, a data frame, a model, and a plot, being able to call out $plot instead of searching to figure out what numbered element of the plot, is much easier.
