Functions are special R objects that take in other objects as arguments and produce something. In many cases, the person who wrote the function provides default values for some or even all the arguments. We've now seen a couple of important functions and techniques. First we saw the concatenate function that was used to create vectors. And we saw we could create vectors that are sequences of integers using the integer colon integer notation. We used the length, head, and tail functions to learn more about vectors. We also saw character vectors. The letters object is a built-in vector of letters inside of R. If we wanted, we could exam the subset of the letters. We also saw how to construct matrices using the matrix function, as well as how to specify the number of rows and columns for a matrix using the second and third arguments. The dim function provided the way to check the dimensions of a matrix. And we could again use brackets to examine a subset of the matrix, except that we spec
