ABSTRACT
If you have rarely or never used R before, the first section of this chapter gives you enough information to be able to get started and understand the R code I use throughout the book. For more detailed introductions on how to use R please refer to the resources I mentioned in Chapter 1 (Section 1.6). Experienced R users might want to skip the first section. In the second section I’ll give a brief overview of RStudio. I highlight the key features of the main RStudio panel (what appears when you open RStudio) and some of its key features for reproducible research. Finally, I discuss the basics of the knitr package, how to use it in R, and how it is integrated into RStudio.
