Hadley Wickham will be at our next meet-up, speaking on "dplyr: Efficient data manipulation for data frames, data tables, databases and more!" His dplyr package is the next iteration of the very popular plyr package for easily manipulating large datasets.
Hadley is truly one of the rock stars of the R community. In addition to dplyr, he is the author of over 30 packages, including ggplot2, reshape, testthat, and devtools. He is currently the Chief Scientist at RStudio.
Our sponsor, Revolution Analytics, will provide the free pizza. Doors open at 5:30, the presentation begins at 6:00.
Please join me in welcoming Hadley to Chicago. I think this will be a meet-up to remember!
