Overview of this book

R is a high-level functional language and one of the must-know tools for data science and statistics. Powerful but complex, R can be challenging for beginners and those unfamiliar with its unique behaviors. Learning R Programming is the solution - an easy and practical way to learn R and develop a broad and consistent understanding of the language. Through hands-on examples you'll discover powerful R tools, and R best practices that will give you a deeper understanding of working with data. You'll get to grips with R's data structures and data processing techniques, as well as the most popular R packages to boost your productivity from the offset. Start with the basics of R, then dive deep into the programming techniques and paradigms to make your R code excel. Advance quickly to a deeper understanding of R's behavior as you learn common tasks including data analysis, databases, web scraping, high performance computing, and writing documents.

Preface

Summary


In this chapter, we went inside R and learned how R functions basically work. More specifically, you learned lazy evaluation, copy-on-modify, lexical scoping, and how environments work to allow these mechanisms. Having a concrete understanding of how R code is run not only helps you write the correct code but also makes it easier to find bugs from unexpected results.

In the next chapter, we will build on top of the foundation laid in this chapter. You will learn the basics of metaprogramming, which enables powerful features of interactive analysis.
