I write about R every weekday at the Revolutions blog: http://blog.revolution-computing.com . In case you missed them, here are some articles from last month of particular interest to R users. http://bit.ly/un680 demonstrated reader Paul Bleicher's code for visualizing a time series as a heat-map calendar. http://bit.ly/5fgis0 and http://bit.ly/mepBH showed (with thanks to Drew Conway) how to use R to perform social network analysis on live data from Twitter. http://bit.ly/KKvSA challenged the R community to recreate an unemployment map created in Python in R. The results (http://bit.ly/11Qve9) were outstanding, and also inspired a similar look at unemployment in Germany (http://bit.ly/2Mywrq). http://bit.ly/4nKQ0w showcased a Brazilian open-government website created by Eduardo Leoni that relies heavily on R. Several media outlets this month looked at the impact of R and IBM's acquisition of SPSS on SAS: Information Management (http://bit.ly/5Qu5mp and http://bit.ly/8VT03b), the New York Times (http://bit.ly/5TRQBi), and Business Week (http://bit.ly/54OoNE). http://bit.ly/8hUr9u related how R graphics were used to illustrate an analysis of the US healthcare reform politics in the New York Times. http://bit.ly/3sM5kQ reviewed R's presence at a data-mining "unconference" in the Bay Area. http://bit.ly/3MZn0r showed how easy it is to install ESS on Ubuntu Linux, for a more productive environment for programming in R. http://bit.ly/6ajtBu looked at some of the unique features of R's function-call semantics. http://bit.ly/7UNSbl was a tongue-in-cheek comparison of Hadoop and R. http://bit.ly/1uxU3w announced REvolution Computing's "R Productivity Environment", an IDE for R on Windows. http://bit.ly/1Qxp9P shares the slides from the Introduction to R talk I have to a Linux User Group in Davis (CA), and some links for R beginners. http://bit.ly/uZRtS linked to a simple analysis of scores from the game Canabalt. Other non-R-specific stories in the last month covered: floating-point errors (http://bit.ly/3UU4SJ), Stochasticity on the radio (http://bit.ly/4NpvRN), breast cancer screening (http://bit.ly/8Y01rs), the Mythbusters (http://bit.ly/8dd3Uz) and on the lighter side: the connection between Tufte and Lord of the Rings (http://bit.ly/5G6o31), a new way of looking at Choose Your Own Adventure books (http://bit.ly/1unnsO), and the Reimann Hypothesis (http://bit.ly/87ieTX).
