This workshop will provide an introduction to graphics in R with ggplot2. Participants will learn how to construct, customize, and export a variety of plot types in order to visualize relationships in data. We will also explore the basic grammar of graphics, including the aesthetics and geometry layers, adding statistics, transforming scales, and coloring or paneling by groups. You will learn how to make histograms, boxplots, scatterplots, line plots, and heatmaps as well as how to make compound figures. The bonus challenge walks you through how to make geographic maps using the Google Maps API.
