- Index
In this chapter, we were introduced to R. We learned that its benefits include being free, cross-platform, open source, programmable, extendable, graphical, and community-supported. We also considered why you should use R to conduct your data analyses and how this book can help you quickly become an experienced R user.
You should now be able to:
- Describe the R Project for Statistical Computing
- Detail how you will benefit from using R
- Explain why R is an essential tool for your work
- Decide why this book is right for you
- List the major topics covered in this book
In the next chapter, we will work through the installation process to prepare R for battle.
