With over 6000 libraries and a rapidly expanding user base R statistical software has become a powerful tool for conducting environmental epidemiology research. Interest in learning R has been strong at ISEE and, as a result, this workshop will be offered at ISEE for the fifth time. The goal of the workshop is to get participants up and running with R, to provide users with enough background to begin manipulating data, preparing graphics and conducting simple statistics. Users will also learn how to install libraries and read and write data in a variety of formats. Data from environmental epidemiology will be used in examples and participants will be expected to use their own laptops. This workshop is designed for beginners and near beginners.
