Social network analysis using R
Social network analysis is a method or tool by which one can analyze
the connections across individuals or groups or institutions.
It allows us to examine how actors (e.g.consumers) or institutions
(e.g.companies) are interrelated.
The advantage of social network analysis is that, unlike many other
methods, it focuses on interaction (rather than on individual
behavior).
A network analysis might assess the network for changes in structure
deriving from technological disruptions.
This tutorial starts with a simple example and draws from another
tutorial by Katherine Ognyanova that has a more in depth look at some of
the features of igraph (2016) of any embedded R code chunks within the
document.
