The upper-left panel is the R Script Editor. Select the link from the “Installers for Supported Platforms” list that corresponds to the operating system appropriate for your computer. This page has directions for installing and configuring Rstudio for use in a Windows operating system and a brief introduction to using RStudio. Among other conveniences, RStudio provides a four-panel layout that includes a feature-rich source-code editor (includes syntax highlighting, parentheses completion, spell-checking, etc.), a tight link to the R console, a system for examining objects saved in R, an interface to R help, and extended features to examine and save plots. RStudio eases the user’s interaction with R by providing some of the conveniences of a GUI and, more importantly, a means for efficiently constructing and running R scripts. RStudio is an open-source integrated development environment (IDE) that serves as a front-end “on top” of R. While such an interface may be unfamiliar to many users, its primary strength is the ability for users to develop scripts of commands to perform various analyses that can then be easily repeated. Unlike many other programs, users interact with R through a command line rather than through a graphical user interface. R is an open-source software environment for statistical computing and graphics that runs on Windows, Mac OS, and many UNIX platforms. Jump to: Installing / Configuring / Introducing
