Title: Airline On-Time Data Set
Author(s): Michael Kane
Companies: Yale University

The 2009 Data Expo centered around the airline on-time performance data set. In total, the data set includes information for over 120 million flights, each with 29 variables related to flight time, delay time, and so on. In total, the uncompressed data set is about 12 gigabytes in size. Exploratory data analysis on a data set this large presents a significant challenge to R users who rely on familiar data structures and familiar statistical functions for analyses. This presentation shows an animated visualization of the data set and proposes solutions to questions, "what is the best time to fly?" and "do older planes suffer more delays?" using the high-performance computing packages bigmemory, foreach, multicore, doMC, and biglm. The goal is to elucidate the usage of these packages in a big-data setting and show how easily they can be incorporated into an R users repertoire
