The Workshop in Methods (WIM) was created in 2009 with the mission of providing introductory education and training in sophisticated research methods to graduate students and faculty in the social sciences at Indiana University. Our goal is to supplement statistics and methods courses across the Bloomington campus with topical workshops led by leading methodological scholars from IU and across the United States.
WIM is currently directed by Patricia McManus, working with the WIM advisory committee and the Social Science Research Commons. The initial idea for WIM began with Scott Long, who discussed his vision with Dr. William Alex Pridemore. Pridemore created WIM and directed the series until 2013.
If you would like to receive updates from WIM – including announcements of upcoming presentations – you can join our mailing list by sending an email request to firstname.lastname@example.org.

Jefferson Davis, "The Grammar of Graphics: An Introduction to ggplot2"
Social Science Research Commons (Woodburn Hall 200), 2-3:30pm
In The Grammar of Graphics, Leland Wilkinson created a systematic way to think about statistical graphics and the presentation of quantitative data. The package ggplot2 by Hadley Wickham implements of Wilkinson's system for the language R.
The talk will discuss the following:
- What are statistical graphs and what are some ways to talk about them?
- Examples of common plot types done in ggplot2.
- Using ggplot2 to display common statistical transformations.
- Grouping and faceting data in ggplot2.
- Using themes to add polish to graphs.
The talk requires no familiarity with ggplot2 or other libraries. Some familiarity with base R, however, will be useful.
Jefferson Davis is a software analyst with Research Analytics. He has worked on several projects that have used R and R libraries. Current projects include work in data visualization, machine learning methods, and large data sets.
