Chapter 1 Introduction To R

Welcome to the programming language R!

Data is art, and as you will read many times in this book:.

R puts the r in Artist.
If you have never even touched R, great! If you have experience with R, great!
This chapter is meant more for people who have never touched R before. It is not meant to make you an expert level programmer, but more to provide the groundwork for programming in R. Before you can do calculus, you need to be able to do addition, subtraction, multiplication, and division.
This chapter is exactly that.
You do not need to memorize this chapter; think of it as a reference you will return to throughout the book.
