This is a comprehensive tutorial on network visualization with R. It covers data input and formats, visualization basics, parameters and layouts for one-mode and bipartite graphs; dealing with multiplex links, interactive and animated visualization for longitudinal networks; and visualizing networks on geographic maps. To follow the tutorial, download the code [...]
This post includes R code and materials from my Computational Social Science course at Rutgers University. The course offers theoretical discussion and hands-on training using R. It is a doctoral seminar offering a gentle introduction to computational methods both for people with some previous experience in coding, and for those who [...]
Since I started posting network tutorials on this site, people will occasionally write to ask me about the included example datasets. I also get e-mails from people asking where they might find network data to use for a project or in teaching. Seems like a good idea to post a quick [...]
More details to follow, but for now: workshop materials from Sunbelt 2016.

In the next few months, I will be running several network visualization workshops using R and Gephi at Sunbelt 2016 (Newport Beach, CA) and Political Networks (St. Louis, MO). The descriptions follow below - if you are going to one of the conferences, do stop by! By popular demand, the workshops [...]
Get the tutorial PDF and code, or download on GithHub. A more recent tutorial covering network basics with R and igraph is available here. If you find the materials useful, please cite them in your work – this helps me make the case that open publishing of digital materials like this [...]

The Data Swap 2013 skill-a-thon organized by The Boston Globe, NULab for Texts, Maps, and Networks, and The Boston Area Research Initiative is taking place on October 17-18. The materials for the quick network tutorial I'm doing there are posted below. DataSwap 2013 network presentation (Download PDF). Visualizing network dynamics: Download [...]
My doctoral dissertation (defended a few months back) studies a dynamic network of news outlets and the topics they cover over time. It implements a measure of media fragmentation and uses actor-based modeling to evaluate the impact of economic, political, organizational, and structural forces on certain properties of the media agenda. [...]
In the fall of 2012, I got to design & lead the weekly labs for a network seminar at USC. I also worked on the methods portion of the syllabus for the class. COMM 645: Communication Networks is a PhD-level course taught by Peter Monge. The labs cover a range of [...]
Once a year, the Annenberg Networks Network (ANN) at USC and the Science of Networks in Communities Laboratory (SONIC) at Northwestern University convene an international seminar on network science. The conference organizers include Manuel Castells, Noshir Contractor, Janet Fulk, and Peter Monge. The seminar that took place at USC this April [...]
Exploring the structure of relationships between news organizations, issues, and audience members is key to understanding the media system. The paper I'm posting here (just presented at ICA 2011, Boston) looks into a range of network types available to media researchers: inter-organizational, semantic, issue, hyperlink, and social graphs. It discusses important predictors [...]
