Data Visualization in ggplot

About this Class

This hour and half online training will explore the topics of perception and cognition, and how these apply to data visualization. This class will also teach you how to visualize your data using ggplot2. We will start by creating a simple scatterplot and use that to introduce aesthetic mappings and geometric objects, the fundamental building blocks of ggplot2. You must have taken Introduction to R and RStudio class to be successful in this class.

By the end of this training, participants should be able to:

•    Describe how perception and cognition inform visualizations
•    Discuss the visual properties that “pop-out," and how these inform visualizations
•    Distinguish between aesthetic mappings and geometric objects, the fundamental building blocks of ggplot2
•    Create a simple scatterplot
•    Create a plot and save it in a high-resolution format

Attendees are expected to have basic understanding of R and RStudio. In order to proceed, attendees should have done the following:

 
1.    Installed R and RStudio 
2.    Taken Introduction to R and RStudio training. If not, here are some resources for getting started: 

•    Introduction to R 
•    Introduction to RStudio 
•    Introduction to Scripts in RStudio
