RStudio
One of the most popular ways to run R has become RStudio. RStudio is a free, open-source integrated development environment (IDE) for R. A screen shot of R Studio is shown in Figure 2-5.
Unlike the standard R GUI, RStudio tiles windows on the screen and puts different windows in different tabs. Additionally, you can install RStudio on a Linux server and access R from a web browser! To learn more about RStudio and download a copy, see http://www.rstudio.org.
