Hi all, Just a short announcement that the 4th Chinese R Conference (ChinaR) will take place at the Renmin University of China (Beijing session) on May 28, 2011. Since 2008 we have been holding ChinaR conferences in Beijing (summer) and Shanghai (winter) each year. This conference is mainly for Chinese R users and gaining more influence in China (see the R News and R Journal for past conference summaries). Some highlights this year range from the introduction to Rcpp and high-performance computing to the application of R in online dating systems. English speakers are welcome as well. There is no registration fee; the conference is completely free (in the sense of both free lunch and free software). Funding is also available for student speakers, thanks to our sponsors. For more details, see http://cos.name/2011/04/chinar-2011/ (in Chinese) Questions can be directed to chinar-2011-bj at cos.name. Thanks!
