Preface

Chapter 1.  Quick Start

Data analysis is difficult without the proper tools. It is almost impossible to extract patterns directly from a large set of numbers aligned in rows and columns and draw any conclusion, even for experts. A suitable tool, such as R, will remarkably boost your productivity in working with data. From my experience, learning a programming language is somehow like learning a human language. It is probably not a good idea to jump right into the details of vocabulary and grammar before looking at the big picture, getting motivated, and starting small. This chapter gives you a quick start by taking an overview of the R programming language in depth.

In this chapter, we will cover the following topics:

  • Introducing R

  • The need for R

  • Installing R

  • Tools required to write R code

As soon as the software and tools are ready to go, you will write a simple R program to experience how it basically works. Once this is done, the R journey will unfold from the basics to advanced techniques and applications.
