The EARL (Enterprise Applications of R) conference is one of my favourite events to go to. As the name of the conference suggests, the focus of the conference is where the rubber of the R language meets the road of it being used to solve real-world problems. Prior conferences have included presentations on how Maersk uses R to optimize capacity for its shipping lines, how Investec has deployed R to support investment and risk teams, how Verizon uses R to analyze cybersecurity data, and how AstraZeneca uses R to design clinical trials. This years conferences, to be held in San Francisco June 5-7, and London September 12-14, promise to be equally fascinating. (The social program is always a lot of fun, too.)
The presentations as EARL conferences come directly from R users, so if you're using R to solve an interesting problem in business, government, or for the public good, then consider giving a presentation yourself. The call for papers closes on April 14 for both San Francisco and London.
Update: The call for papers has been extended to April 14.
