Advanced R, Second Edition (Chapman & Hall/CRC The R Series)

<b>Advanced R</b> helps you understand how R works at a fundamental level. It is designed for R programmers who want to deepen their understanding of the language, and programmers experienced in other languages who want to understand what makes R different and special. <br /> <br />This book will teach you the foundations of R; three fundamental programming paradigms (functional, object-oriented, and metaprogramming); and powerful techniques for debugging and optimising<br />your code.<br /><br />By reading this book, you will learn: <br /> <ul> <br /><li>The difference between an object and its name, and why the distinction is important</li> <br /> <br /><li>The important vector data structures, how they fit together, and how you can pull them apart using subsetting </li> <br /> <br /><li>The fine details of functions and environments </li> <br /> <br /><li>The condition system, which powers messages, warnings, and errors</li> <br /> <br /><li>The powerful functional programming paradigm, which can replace many for loops</li> <br /> <br /><li>The three most important OO systems: S3, S4, and R6</li> <br /> <br /><li>The tidy eval toolkit for metaprogramming, which allows you to manipulate code and control evaluation</li> <br /> <br /><li>Effective debugging techniques that you can deploy, regardless of how your code is run</li> <br /> <br /><li>How to find and remove performance bottlenecks</li> <br /></ul> <br />The second edition is a comprehensive update: <br /> <ul> <br /><li>New foundational chapters: "Names and values," "Control flow," and "Conditions" </li> <br /> <br /><li>comprehensive coverage of object oriented programming with chapters on S3, S4, R6, and how to choose between them</li> <br /> <br /><li>Much deeper coverage of metaprogramming, including the new tidy evaluation framework</li> <br /> <br /><li>use of new package like rlang (rlang.r-lib.org), which provides a clean interface to low-level operations, and purr (purrr.tidyverse.org/) for functional programming</li> <br /> <br /><li>Use of color in code chunks and figures</li> <br /></ul>
