There are many network repositories out there that offer a large variety of amazing free data.
(See the awesome network analysis list on github for an overview.)
The problem is, that network data can come in many formats. Either in plain text as edgelist or adjacency matrix, or in a dedicated network file format from which there are many (paj,dl,gexf,graphml,net,gml,…). The package
igraph has an import function for these formats (
read_graph()) but I have found it to be unreliable at times.
networkdata package collates datasets from many different sources and makes the networks readily available in R.
The data is very diverse, ranging from traditional social networks to animal, covert, and movie networks. In total, the package includes 979 datasets containing 2135 networks. As such, I hope this package to be a good resource for teaching, workshops and for research if example data is needed. You can only get so far with the Karate network.
Due to the nature of the package (only data, no functions), it will not go to CRAN at any point. However, the package is available via drat (If you are looking for stable builds of the package). With drat, you can install and upgrade non-CRAN packages directly from R using the standard
# install.packages("drat") drat::addRepo("schochastics") install.packages("networkdata")
To save on line of code in the future, you can add
drat::addRepo("schochastics") to your
The developer version is available via github.
The required space for the package is ~22MB, given that it includes a lot of data.
So far, the package includes datsets from the following repositories:
- Freeman’s datasets from http://moreno.ss.uci.edu/data including most of the classical (small) datasets in social network analysis.
- The movie networks from https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/T4HBA3 includes interactions among characters in 773 movies which were automatically parsed from scripts.
- Covert networks from https://sites.google.com/site/ucinetsoftware/datasets/covert-networks. Around 50 datasets of networks with different criminal activities (drugs, terrorism, etc.). This dataset was originally compiled by the Mitchell Centre for SNA.
- Animal networks from https://bansallab.github.io/asnr/. A large collection of networks with different interactions (dominance, grooming, etc.) in groups of different species.
- Shakespeare’s plays networks build with data from https://github.com/mallaham/Shakespeare-Plays. Similar to the movie dataset. Includes scene co-appearances of characters in 36 plays of Shakespeare.
- Some networks from http://konect.uni-koblenz.de/. Konect is a large repository of network data. Only a view small datasets are included from there.
- Tennis networks compiled from https://github.com/JeffSackmann (please give credit to him if you use this data). Includes all matches between 1968 and 2019 (both WTA and ATP) as yearly networks. The networks are directed, pointing from loser to winner with the surface (hard, grass, etc) as edge attribute.
- Some random datasets I had lying around (e.g. the “Grey’s Anatomy” hook-up network)
All networks are in
igraph format. If you are used to work with the
network format (as in
ergm), you can use the intergraph package to easily switch between
A list of all datasets can be obtained with
data(package = "networkdata")
Alternatively, use the function
show_networks() to get a list of
datasets with desired properties.
