I write about R every weekday at the Revolutions blog: http://blog.revolution-computing.com and every month I post a summary of articles from the previous month of particular interest to readers of r-help. http://bit.ly/a4iVi5 linked to slides and video from a 30-minute "Introduction to R" talk I gave on January 28, with links to many useful R resources. http://bit.ly/cfhrO1 brought news that R's creators Robert Gentleman and Ross Ihaka have jointly won the inaugural Statistical Computing and Graphics Award from the ASA. http://bit.ly/6CVPcz welcomed Robert Gentleman to REvolution Computing's board of directors. http://bit.ly/5g6Sxu announced the print availability of the new book from O'Reilly, R in a Nutshell. It has a harpy eagle on the cover. http://bit.ly/5RfnJG showed how to use calendar heatmaps to analyze traffic on a FriendFeed group. http://bit.ly/7agloZ showed that the number of R packages is growing exponentially. The evidence comes from a paper in the first edition of the R Journal, updated with more recent data here: http://bit.ly/749Kfn http://bit.ly/504UEz showed R being used to evaluate biases in survey questions. http://bit.ly/d5ZMcv linked to slides and video from talks by Jeff Horner and Jeroen Ooms on "R-Powered Web Apps". http://bit.ly/7pHzLY linked to slides from the New York R User Group "R Rosetta Stone" meeting, with tips on coming to R from SAS, Matlab, SQL, Clojure or Python. http://bit.ly/51BBO0 linked to Bob Muenchen's table of equivalent R packages to modules in SAS and SPSS. http://bit.ly/colWqf linked to a review of new features in version 0.85 of the ggplot2 package. http://bit.ly/7XC5Nh called for presenters at the useR! 2010 conference, and announced a commercial applications track. http://bit.ly/5GwPRx linked to a step-by-step tutorial on how to make a heat map with R. http://bit.ly/8GKgab looked at two analyses of a surprise upset in a US Senate election done with R (one done on 64-bit Windows with the REvolution R Enterprise build). http://bit.ly/9CF0Rb gave some examples from the new RgoogleMaps package of combining satellite maps with data in R. http://bit.ly/bSmZRD showed off a very creative use of ggplot2 to illustrate the history of colors in a box of Crayola crayons. Several new local R user groups are starting up: Seattle, USA (http://bit.ly/9pat0Z), Philadelphia (http://bit.ly/4ATi22), and Washington, DC (http://bit.ly/4ATi22). Other non-R-specific posts in the past month covered data visualizations in the New York Times and the Wall Street Journal (http://bit.ly/7I3QVh), what programmers ought to know about Statistics (http://bit.ly/9JZeEV) and (on a lighter note) visualizing gravity wells (http://bit.ly/bn7fxz).
