Here you’ll find workshop slides and content. They are roughly in order of how recently they’ve been given (or will be). Some are not so much workshops as talks without any expectation of hands-on exercises or similar. Check out the schedule to see times/dates for these as well as other CSCAR events (we give a lot of workshops!).

Recent talks…

If you’re looking for the notes for a recent workshop I’ve given, you’ll find it here.


For 2020 I’m doing an R Series covering various topics, the content of which is all found here: Data Processing and Visualization in R (more details about this document below).

The intention is to cover five key topics: basic information processing, programming, modeling, visualization, and publication/presentation.

Other workshops will be added as I get to them.


This year I’ve taken a bit of a different tack with my workshops using notebooks and a much more interactive style. The repositories containing the notebooks can be found here.


These are the texts that serve as the basis for the workshops.

Easy Bayes with rstanarm and brms
This workshop provides an overview of the rstanarm and brms packages. Basic modeling syntax is provided, as well as diagnostic checking, model comparison (posterior predictive checks , WAIC/LOO ), and how to get more from the models (marginal effects , posterior probabilities posterior probabilities, etc.).

Data Processing and Visualization in R
Focus is on common data processing and exploration techniques, especially as a prelude to visualization. Part of the focus will be on dplyr and tidyverse, which enhance and facilitate the sorts of operations that typically arise when dealing with data, including faster I/O and grouped operations. For visualization, the focus will be on using ggplot2 and other packages that allow for interactivity. Exercises may be found in the document as well (including Jupyter notebooks of the same demonstrations in Python).

Introduction to R Markdown
This workshop will introduce participants to the basics of R Markdown. After an introduction to concepts related to reproducible programming and research, demonstrations of standard markdown as well as overviews of different formats will be provided, including exercises.

Factor Analysis and Related Methods
This workshop will expose participants to a variety of related techniques that might fall under the heading of ‘factor analysis’, latent variable modeling, dimension reduction and similar, such as principal components analysis, factor analysis, and measurement models, with possible exposure to and demonstration of latent Dirichlet allocation, mixture models, item response theory, and others. Brief overviews with examples of the more common techniques will be provided.

Text Analysis with R
This document covers a wide range of topics, including how to process text generally, and demonstrations of sentiment analysis, parts-of-speech tagging, and topic modeling. Exercises are provided for some topics. Some Python examples will also be added at some point.

Mixed Models with R
This workshop focuses on mixed effects models using R, covering basic random effects models (random intercepts and slopes) as well as extensions into generalized mixed models and discussion of realms beyond.

Structural Equation Modeling
This document regards a recent workshop given on structural equation modeling. It is conceptually based, and tries to generalize beyond the standard SEM treatment. The document should be useful to anyone interested in the techniques covered, though it is R-based, with special emphasis on the lavaan package.

Been awhile…

These haven’t been given in at least a year or so. The content is still likely useful, but until updated or given again, you may also find a more fully fleshed out related work on the documents page.

My God, it’s full of STARs! Using astrology to get more from your data.
Talk on structured additive regression models, and generalized additive models in particular.

Become a Bayesian in 10 Minutes
This document regards a talk aimed at giving an introduction Bayesian modeling in R via the Stan programming language. It doesn’t assume too much statistically or any prior Bayesian experience. For those with such experience, they can quickly work with the code or packages discussed. I post them here because they exist and provide a quick overview, but you’d get more from the more extensive document.

Engaging the Web with R
Document regarding the use of R for web scraping, extracting data via an API, interactive web-based visualizations, and producing web-ready documents. It serves as an overview of ways one might start to use R for web-based activities as opposed to a hand-on approach.

Ceci n’est pas une %>%
Exploring your data with R. A workshop that introduces some newer modes of data wrangling within R, with an eye toward visualization. Focus on dplyr and magrittr packages.

Getting More from RStudio
An afternoon talk on how to use RStudio for more than just coding.

Possible future topics

Shiny basics


R Bootcamp
An afternoon workshop I hope to develop further at some point.
