A quick reminder that two competitions based around data analysis, both very suited to R, are currently underway.
First, there's still plenty of time to enter the competition to predict popular R packages, announced by the The Dataists and hosted at Kaggle. According to organizer Drew Conway, the competition has already received 114 entries from 21 teams. But with 13 weeks of competition remaining, there's still plenty of time to oust the leader (who is currently scoring 0.982349 AUC on the test data). I've also heard that new data may be added to the competition soon, which should shake things up a bit. And to encourage even more participation, Revolution Analytics has chipped in an additional prize for the winner: a 32Gb iPod Touch. See the announcement at The Dataists for info on how to join the fray.
Second, the How Do People Use Firefox data visualization competition, announced earlier this month, is now underway. The data from the Mozilla Test Pilot program is now live, ripe for some insightful visualizations – the ggplot2 package in R will likely be the tool of choice for many of the entrants. Check out the discussion forum to see what others are doing, and the main competition page for details on how to enter. The deadline for submissions is December 15.
