Social Network Analysis This post presents an example of social network analysis with R using package igraph. Professor Megan Squire is a Senior Fellow at CARR, and a Professorof Computer Science at Elon University, North Carolina. Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. Using SNA to model a network reveals many interesting patterns in the structure of the network that would not be apparent otherwise.

For example, SNA can reveal the most important nodes in the network – the ones who everyone seems connected to – or can reveal nodes that are entirely disconnected from the rest of the network. Still others have used SNA to uncover networks of hyperlinks or networks of ideological concepts that exist between extremist hate group websites. It characterizes networked structures in terms of nodes (individual actors, people, or things within the network) and the ties, edges, or links (relationships or interactions) that connect them. © Megan Squire.
