The slides and videos from Jeff Horner’s talk at last week’s Bay Area User Group session on R-Powered Web Apps are now available. I’ve embedded it here below, but you might want to click through to larger size for better readability on the slides.

Jeff’s talk (titled “Use Rapache! It works”) gives an overview of how to integrate R into web-based applications with the Rapache platform. (Jeff is the maintainer of the Rapache project.) During the talk he points to several examples of Rapache in action, which you might want to check out yourself:

• Polyart: Create fractals in R from the process of root-finding in a function you specify
• Power and sample size calculations (from the spower function in Hmisc)
• Bivariate baseball score plots
• PitchFX viewer for visualizing baseball pitcher performance
• Bay Area water pollution

Thanks go to Drew Conway for uploading the videos at VCASMO so that everyone can share in these local user-group talks. Drew is paying for the hosting himself, so if you enjoy these videos please consider contributing to his hosting fund. (We’ve contributed here at REvolution Computing as part of our program to support local R user groups.)

Unfortunately the video of Jeoren’s talk from the meeting last week isn’t yet available, but if you’re in the LA area, you can see a live version of Jeroen’s talk tonight. (Update Jan 22: video now available!)
