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 [...]
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 and [...]
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. Basic and Advanced Network Visualization with Gephi Sunbelt 2016 workshop materials Network visualization with Gephi: workshop handout (PDF) Network visualization with Gephi: example data files (ZIP) Basic and Advanced Network Visualization with R Sunbelt 2016 workshop materials [...]
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 [...]
A new Politico post produced by our lab examines the mentions of countries around the globe in congressional documents. We look at the frequency of country mentions and co-occurrence. These numbers were extracted from political statements provided by VoteSmart. Here we post the data we used for those visualizations. The files [...]
If you are interested in analyzing the deleted tweets of politicians, my new R package PolitwoopsR is available on GitHub. Also see this R script examining deleted tweets. [Update 15/04/02] If you were brought here by a Dean Richards Twitter bot, read this. A few days ago I published [...]
Politicians Descriptive Party States URLs Terms/Tags Sentiment Term net [UPDATE 15/03/30] Check out this follow-up post to get the R code used to extract and clean the Politwoops & Twitter data. A package that automates the data collection is now available on GitHub: PolitwoopsR. For some months now, I've been playing [...]
Facebook Network: Gephi Facebook Network: igraph Facebook Network: qgraph [Update April 26 2o14] Esteban Moro reminded me that there's no need to manually rescale igraph layouts now - one can use layout.norm() instead (script updated accordingly). Hugle [...]
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 [...]
