Chapter 2. Efficient Setup

An efficient computer setup is analogous to a well-tuned vehicle. Its components work in harmony. It is well serviced. It’s fast!

This chapter describes the setup that will enable a productive workflow. It explores how the operating system, R version, startup files, and IDE can make your R work faster. Understanding and at times changing these setup options can have many additional benefits. That’s why we cover them at this early stage (hardware is covered in Chapter 3). By the end of this chapter, you should understand how to set up your computer and R installation for optimal efficiency. It covers the following topics:

R and the operating systems

System monitoring on Linux, Mac, and Windows

R version

How to keep your base R installation and packages up-to-date
