Advanced R Solutions

<p>This book offers solutions to all 284 exercises in <b><i>Advanced R Second Edition</i></b>. All the solutions have been carefully documented and made to be as clear and accessible as possible. Working through the exercises and their solutions will give you a deeper understanding of a variety of programming challenges many of which are relevant to everyday work. This will expand your set of tools on a technical and conceptual level. You will be able to transfer many of the specific programming schemes directly and will discover far more elegant solutions to everyday problems.</p><p>Features:</p><ul> <p> </p> <li>When R creates copies and how it affects memory usage and code performance</li> <p> </p> <li>Everything you could ever want to know about functions</li> <p> </p> <li>The differences between calling and exiting handlers</li> <p> </p> <li>How to employ functional programming to solve modular tasks</li> <p> </p> <li>The motivation mechanics usage and limitations of R's highly pragmatic S3 OO system</li> <p> </p> <li>The R6 OO system which is more like OO programming in other languages</li> <p> </p> <li>The rules that R uses to parse and evaluate expressions</li> <p> </p> <li>How to use metaprogramming to generate HTML or LaTeX with elegant R code</li> <p> </p> <li>How to identify and resolve performance bottlenecks</li> </ul>
