Introduction

This chapter covers the basic programming syntax functions and capabilities of R. It has been put forward to introduce you to R and accelerate your learning. The objectives are as follows:

  • Install R and RStudio

  • Create and explore vectors

  • Create data frames and matrices

  • Explore mathematical and statistical functions

  • Build simple plots

  • Install and load packages

All of the examples in this appendix are covered in one way or another in the preceding chapters. However, if you are completely new to R, this is a great starting point. It may accelerate your understanding of the content in the chapters.
