From Business Intelligence to advanced statistics applications, professionals are expected to access and manipulate large datasets, and R is the perfect tool for it. In this introductory chapter, we explain the principles of programming and the position of R in data science today. Then, a beginners level course on R starts introducing the main data types of this superior programming language. Examples and exercises are included to provide a hands-on training, guaranteeing the users control and understanding of R capabilities. Then, two main generic programming tools are introduced: control structures and functions. This will allow us to manipulate our datasets and generate all sorts of values and conclusions. In addition, this chapter includes specific R operators that highly simplify the use of R and enhance its capabilities. |
