RCloud: An HTML5 frontend for collaborative data analysis in R

RCloud is an environment for collaboratively creating and sharing data analysis scripts in R. Much like Sage, iPython notebooks and Mathematica, RCloud provides a notebook interface that lets you easily record a session and annotate it with text, equations, and supporting images.

Unlike these other systems, RCloud:

• lets you easily browse other users's notebooks, comment on notebooks, fork notebooks, star notebooks, and use them as function calls in your own notebooks.
• provides an environment in which R packages can create rich HTML content (using, for example, d3 and dc.js).
• provides a transparent, integrated version control system. In essence, RCloud never forgets what you did. If you need low-level access to RCloud notebooks, you can simply clone the associated git repository. This is because RCloud notebooks are Github gists.
