This book offers solutions to all 284 exercises in Advanced R, Second Edition. 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.Features:When R creates copies, and how it affects memory usage and code performanceEverything you could ever want to know about functionsThe differences between calling and exiting handlersHow to employ functional programming to solve modular tasksThe motivation, mechanics, usage, and limitations of R's highly pragmatic S3 OO systemThe R6 OO system, which is more like OO programming in other languagesThe rules that R uses to parse and evaluate expressionsHow to use metaprogramming to generate HTML or LaTeX with elegant R codeHow to identify and resolve performance bottlenecks
