Episode 8: Visualization With `Ggplot2`

Posted on Wednesday, Jun 20, 2012 | Category: Podcast
I’m happy to present this jam-packed episode of the R-Podcast dedicated to using the ggplot2 package for visualization. This episode will have a companion screencast released in the next few days. I use data from the Hockey Summary Project to demonstrate how to create a series of boxplots of NHL regular season attendance for each team. The R code used in this episode will be available via GitHub. I also extend my thanks to the Going Linux podcast for plugging the R-Podcast. If you are interested in providing a listener tip about R, please call the voicemail hotline at +1-269-849-9780 or record an audio clip and send it tothe Rcast(at)gmail.com. Please keep the wonderful feedback coming and hope you enjoy this episode!
