Polls can be an incredibly valuable tool for understanding politics and are a central component of campaign analysis from policy experts, commentators, and even the candidates themselves. In this course you’ll explore the uses of polling data by examining summary statistics and visualizations of polls from the 2016 Republican and Democratic primaries using base R plots, the ggplot2 package, and the googleVis package.
