Merry Christmas is.R() readers! Thanks for accompanying us through an excellent first semester of R blogging, and for your feedback and enthusiasm. To celebrate, we’ve built an image mosaic from the shiny, happy avatars of our over 600 (!) Twitter followers. We’ll be back in 2013 with even more tutorials and unnecessarily contrived examples, and we hope you’ll continue to visit, pose hard questions, and explore R with us.
