1.2 Overview of the book structure
- The book is composed of five sections. A step by step path towards mastering R techniques.
- The Foundations is the part in which the R components will be examined. It will help understanding how to use all the basics tools to deal with functions and structures.
- The Functional programming goes a little more in dept into programming with R, making functions of functions. Describing function factories and operators.
- The Object-oriented programming - OOP is a five chapter section, all about object oriented systems among S3, R6 and S4.
- The Metaprogramming section introduces you through the programming layers.
- Finally, the Techniques section is dedicated to finding and fixing bugs and improving performances.
1.2.1 What this book is not
- This book is about the R programming language, not R as the data analysis tool.
- Other books cover this topic.
- R for Data Science.
- We will not be discussing package development at length.
- Some experience using R will be helpful.
- I encourage all to participate, though.
1.2.3 Foundations
Six chapters to learn the foundational components of R.The last chapter “conditions” describe errors, warnings, and messages.
1.2.4 Functional programming
This part of the book is dedicated to functions: function factories and operators.
1.2.5 Object-oriented programming
OOP is the most dense part of the book, as it mentions about systems which interact with R.
