[R] ggplot2 case study competiton and wiki

[Garrett Grolemund]

Hi all,

We've moved the ggplot2 wiki to a new location to make it more useful,
http://github.com/hadley/ggplot2/wiki.  To publicize the new location,
we’re organizing a second ggplot2 case study competition. Some great
prizes are at stake:

* grand prize will be a 32GB ipod touch generously donated by
Revolution Analytics.

* two runner ups will receive a free Use R! book of their choice
generously donated by Springer.

To enter, write up a small case study where you’ve found ggplot2
useful and add it to the wiki home page. The deadline for entry is
October 1, 2010. See
http://github.com/hadley/ggplot2/wiki/Case-study-competition for more
details, as well as for example submissions from last year's
competition.

Good luck,

Garrett and Hadley
