Data visualization using R

October 6, 2021 @ 11:00 am - 3:00 pm


A 4-hour workshop taught by Mariola Moeyaert, Ph.D.



Data visualization is the quickest and most powerful technique to understand new and existing information. Exploratory data analysis (EDA) through visualizations marks the starting point of each data science project. The graphs produced during the EDA can inform which data analytic technique is best suitable. The data visualization can help communicate data science findings.

This workshop will guide you on how to think about good data visualization. Through a series of examples, you will learn how to use ggplot to make graphs piece by piece. The emphasis throughout is on acquiring a practical feel for, and good judgement about, the way ggplot can be used, from the simplest cases to sophisticated, highly customized data visualizations.

The workshop is hands-on, and annotated R code, together with data sets and detailed content slides, will be shared. Participants new to RStudio are recommended to take the workshop Introduction to the R statistical computing environment.

The R statistical programming language and computing environment is a free, open-source package for statistical analysis. R has become the de-facto standard in statistics (see Muenchen, 2018; Suda, 2017) and is widely used in the social, health, physical, and computational sciences. Researchers transition to R because it is powerful, flexible, makes routine data analysis easy and has a large and rapidly growing community of users.

Participants are strongly encouraged to have the most recent version of R installed. Participants are also encouraged to download and install RStudio, a front-end for R that makes it easier to work with. RStudio will be used during the workshop. This software is free and available for Windows, Mac, and Linux platforms.

Expected outcomes

After attending this workshop, participants will be able to use RStudio to create good data visualizations. The participants will understand the RStudio syntax needed to create the visualizations, preparing them to apply the syntax to their own data. Participants will understand the basic principles behind effective data visualizations, and how they are implemented in RStudio and ggplot. They will become confident and fluent using ggplot, in order to make, refine, and effectively present good data visualizations.

Pricing and schedule

Time: Wednesday, October 6, 11AM to 3PM (EST)
Cost: $200
Location: Online

We offer $50 discounts for graduate students and $25 discounts for multiple workshop enrollments. Find out about our discounts here.

The main workshop material is scheduled for four hours. Time permitting, Dr. Moeyaert will answer questions about participants’ specific research projects. Participants can ask questions via chat, microphone, or telephone. In order to allow sufficient time for questions, the number of workshop participants is limited to 30.

Who should attend?

The workshop is designed for those who want to become fluent in using RStudio create good data visualizations using ggplot.

About the instructor

Dr. Mariola Moeyaert is an Associate Professor Statistics within the division of Educational Psychology and Methodology at UAlbany. She received her PhD in Educational Statistics from the Katholieke Universiteit Leuven (KU Leuven) in Belgium and worked as a Postdoctoral fellow at the Center of Advanced Study in Education at the City University of New York. Her major research interests and publications are in the field of multilevel analysis, meta-analysis and interrupted time series analysis. She is also interested in Bayesian statistics, bootstrapping, structural equation modeling, longitudinal data analysis, and international comparative research. She (co)authored about 47 international publications, in such journals as Psychological Methods, Multivariate Behavior Research, Journal of School Psychology, Behavior Research Methods, School Psychology Quarterly, etc., reporting about developments in research methodology (including several computing intensive Monte Carlo simulation studies) and about applications of statistical models on educational/medical data. Currently, she is involved as PI and Co-PI in research projects funded by the Institute of Education Sciences about methodological advancements in the field of multilevel meta-analysis.
