Let me show you how it works, explain the confusion, explain an alternative, and then show you how to actually use it. So to demonstrate setNames, I need a vector. And we'll create one called thisVector. And then I also need a vector of vector names to name that vector. So I've created a second vector called vectorNames. Now, let's use setNames to set the name of each thisVector element to the name of vectorNames. First, we'll let's take a look at the raw thisVector. And you can see that it's just the three names that are in the vector, bibbity, bobbity, and boo. Now if I use setNames, thisVector, and I name the elements in thisVector with vectorNames, you'll see that I now have the original three elements of thisVector, bibbity, bobbity, boo, along with the names of each element in the vector. So across the top…
