Data visualization and R

Presenter 1
Ryan Womack
Rutgers University

This workshop will focus on principles and techniques for the visualization of data, with an equal emphasis on theory and implementation. Drawing on classic works by Cleveland (Visualizing Data), Tufte (The Visual Display of Quantitative Information), and Wilkinson (The Grammar of Graphics), a range of best practices for visualization will be illustrated. Recently developed techniques for large-scale, 3D, and interactive visualization will also be discussed. This discussion will be based on works such as Graphics of Large Datasets: Visualizing a Million (Unwin, Theus, and Hofmann), the Handbook of Data Visualization (Chen, Hardle, and Unwin), and Trends in Interactive Visualization: A State of the Art Survey (Liere, Adriaansen and Zudilova-Seinstra) For each of these approaches, methods for creating similar graphics in the R open-source statistical language will be demonstrated, using packages such as ggplot2, lattice, and rggobi. Interactive visualization packages such as shiny and healthvis will also be explored. Prior familiarity with R is helpful but not required.
