Workshop on graphics in R by author of ggplot, Washington DC, 30-31 July

Hadley Wickham, author of the excellent ggplot2 package for R, is presenting a 2-day workshop on graphics in R. The course will naturally include discussion of both static graphics (with ggplot2) and dynamic and interactive graphics (with Ggobi).  The course will be held July 30-31 in Washington DC (perfect if you plan to attend JSM 2009.)
