In this workshop, participants will learn to visualize data using the R package, “ggplot2”. ggplot2, named for the “grammar of graphics”, is a (free and open source) popular and flexible plotting system that is well suited to multivariate data exploration as well as developing graphics for academic publication and popular science communication. In this workshop, we will introduce the ideas behind the grammar of graphics, briefly identify the structure of data required for plotting with ggplot2, and work together through examples that will give participants the tools they need to use ggplot2 in their own data visualization projects. Participants will leave with sample scripts that can be modified for use with their own data and a list of resources for learning more. Participants are encouraged to bring a laptop with a recent (2016 or later) installation of R and RStudio.
