R Python Bridge rpy2 (Laurent Gautier)
R has gained a well-deserved notoriety for statistics, data analysis, and visualization: data experts use it. A lot. The code written for a given data analysis can sometimes become the starting point of an application as colleagues and collaborators express the wish to have an easy way to run the code on their own, perform the task on new data, and tweak parameters. The Python-R bridge "rpy2" can be usedin those situations, with Python the glue language to develop applications while the R parts are kept as the statistics and data analysis engine. After presenting briefly the integration between the two languages, I will demonstrate how a web application can be developed around an existing R script.

Bio: Laurent Gautier I was trained as an engineer in France and I started using R over a decade ago. I have worked mostly on biology and health-related data,which provided me with the opportunity to be an original core member in the Bioconductor team during my PhD, and I have crossed repeatedly the barrier between industry and academia. I am currently serving as Senior Researcher and Head of Core Facility at the Technical University of Denmark.

The RBrowserPlugin Project (Gabriel Becker)
Interest in displaying and interacting with data on the Web has been steadily growing as Web-related technologies grow and mature.  In contrast to creating interactive displays within R to be displayed separately in a Web browser, we can more fully exploit the many new Web-based data visualization technologies by making R available in the Web browser at viewing time. We present the RBrowserPlugin project, which embeds R within a plugin for multiple modern  Web Browsers, allowing bi-directional communication between R and the Web Browser's JavaScript engine.  With R available at viewing time, new statistical
calculations can be performed and displayed dynamically and  interactively in Web pages. This, combined with the ability to fully control and modify Web pages using R and/or JavaScript code, allows us to build rich, data-driven web experiences which combine the
interactive capabilities of JavaScript and HTML5 with the statistical capabilities of R and its many packages. RBrowserPlugin also allows us to display live, interactive, object-based R graphics directly in Web pages. Finally, RBrowserPlugin allows R to interact with other client-side technologies, such as Google Earth and Google maps, allowing for even
richer interaction. We will showcase these functionalities, discuss the details of our communication model, explore possible uses, and contrast RBrowserPlugin with other R based Web technologies.

Bio: Gabriel Becker
Gabriel Becker received a double Bachelor's degree in Mathematics and Statistics from California Polytechnic State University in 2008. Currently he is a PhD Candidate in Statistics at the University of California, Davis under advisor Duncan Temple Lang. Additionally, for the past 2 years, he has worked on R related projects as a contractor for Robert Gentleman's research group within Genentech Research and Early Development's Bioinformatics and Computational Biology department. He is the author of the SearchTrees package for fast neighbor and rectangular query look-up in 2-dimensional space, as well as (with Duncan Temple Lang) the RBrowserPlugin framework for leveraging R as a scripting language within Web Pages.

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.

Henry, started Reno Motorcycle Riders
