R-Powered Web Apps (with Jeff Horner & Jeroen Ooms)

  • January 12, 2010 · 6:30 PM
  • This location is shown only to members

We'll have two presentations on R-driven web applications with Jeff Horner, creator of the RApache module, and Jeroen Oons, a visiting scholar at UCLA. Door will open at 6:00pm, and talks will begin at 6:30pm. Bringing the Power of R to Web Apps with RApache

Jeff Horner will discuss the motivation for creating RApache, a module for executing R code inside of Apache, outline the details for getting a basic R-powered web app running, and highlight some examples of RApache apps & dashboards around the web.

Jeff is the author of several R packages, including Brew (a report generation tool) & Cairo (for graphics), and currently maintains the RMySQL package for interfacing R with MySQL. By day, he is a Systems Analyst at Vanderbilt University.

Developing Web Apps with R and Javascript

Jeroen Ooms will speak about developing web applications with R and Javascript, including exposing one of R's most powerful visualization packages, ggplot2, as a web application.

Some of his work is showcased at:

Jeroen is a visiting scholar from the Netherlands at UCLA Dept. of Statistics. He obtained his MS in Statistics last year from Utrecht University, and he has used R extensively in developing web applications. A Word from Our Sponsor: Twitter, Inc.

    Great presentations.

    Jeff Horner - first off, great work on Rapache, and totally dug your sense of humor :) Would have been great to see a demo. Definitely will look into it as an alternative to RServe in how our open source software OpenI (www.openi.org) interfaces with R. Also curious how hard it will be to run asynchronous R jobs via this interface. For e.g. if I know my R script is going to run for long - how can I kick it off via a web interface, and have some sort of notification when it's done?

    Jeroen Ooms - great work with the UI, will definitely explore more. Still curious about if there's a way to use something like Canvas or Flex for the front-end UI and use R mainly for number-crunching and perhaps provide the "baseline" visualization that Flex/Canvas can either build on or replicate

    Is there a videocast of the event available somewhere?

    Thanks to everyone who chipped in for the pizza. We used most of our REvolution Computing sponsorship money flying Jeroen up for the meeting, so we only subsidized the pizza this time. Thanks all for coming to a great session!

    There was some confusion over donations - when I signed in, I was asked for a $5 donation for pizza, which I gave. Later on, David from Revolution was thanked for sponsoring the pizza. Some more coordination would be appreciated.

    I was surprised about the architecture of Rapache. Clearly even after so long web based statistics is still in its infancy.
    How people are structuring web applications is interesting and the talks did their jobs, set me thinking about how to address some of the limitations.
    Good speakers, good session.

    I was a little disappointed. For Jeff's presentation it would have been more helpful if he had discuss further the last slide that displayed the bay area and developed the conversation around the code that produce the web page. It would have been nice to see more how R and apache work together. On Jeroen presentation he had my attention until his youtube presentation. It was extemely fast and hard to follow, but what I could capture made it look promising. It would have been better for him to walk us through the live version instead of the youtube version.

    Good point! Be sure to bring up next week. "non-profit" - one of topics I want to discuss - becoming an official non-profit entity.

    Any lawyers in group? Friends of lawyers??

    As a non-profit, would BARUG provide any R services to society at large in addition to the R community? To other non-profits? What of R as a public service resource for crowdsourcing?
