Chapter 1. Overview, Installation

This book introduces users to the RStudio™ Integrated Development Environment (IDE) for using and programming R, the widely used open-source statistical computing environment. RStudio is a separate open-source project that brings many powerful coding tools together into an intuitive, easy-to-learn interface. RStudio runs in all major platforms (Windows, Mac, Linux) and through a web browser (using the server installation). This book should appeal to newer R users, students who want to explore the interface to get the most out of R, and long-time R users looking for a more modern development environment.

RStudio is periodically released as a stable version, and has daily releases in between. This book describes the stable release 0.95, which introduced many new features to RStudio: projects for organizing code, powerful code navigation tools, and integration with two popular version control systems.

We will begin with a quick overview of R and IDEs before diving into RStudio.

What is R?

R is an open-source software environment for statistical computing and graphics. R compiles and runs on Windows, Mac OS X, and numerous UNIX platforms (such as Linux). For most platforms, R is distributed in binary format for ease of installation. The R software project was first started by Robert Gentleman and Ross Ihaka. The language was very much influenced by the S language, which was originally developed at Bell Laboratories by John Chambers and colleagues. Since ...
