This post linked to slides and video from talks by Jeff Horner and Jeroen Ooms on "R-Powered Web Apps".

This post 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 in the USA: Seattle, Philadelphia, and Washington, DC.

Other non-R-specific posts in the past month covered data visualizations in the New York Times and the Wall Street Journal, what programmers ought to know about Statistics, and (on a lighter note) visualizing gravity wells.

The R Community Calendar has also been updated.
