RStudio Keyboard Quick Reference by Freakalytics

RStudio-example-ggvis-interactive-graphs-300At Freakalytics, we frequently use R (often referred to as RStats) in our client projects and wanted to share our success using the RStudio Interactive Development Environment (IDE) with you. So, we created the RStudio® Keyboard Quick Reference by Freakalytics. It is available to you, compliments of Freakalytics, as a PDF and later in this article as a searchable data table.
 
 
The RStudio IDE was built by the team at RStudio to make you more productive in the R world. It is a free, open source application for Windows, Linux, Mac and UNIX desktop users. RStudio Desktop includes an interactive R console, a smart editor that supports direct code execution, graphing interfaces, code history, a debugger and project management for R code and related files.
 
Download the RStudio® Keyboard Quick Reference by Freakalytics. The reference card is available as a PDF download for your convenience. The PDF version is printable and usable in most e-book applications.
