The Graph of the Complex Exponential Function. optional arguments passed to ggraph::create_layout(). Both of the arguments for ggraph() are built around igraph. Networks are used to describe and model various real-world phenomena such as social relationships or communications, transportation routes, electrical power grids, molecular interactions, etc. Graphs model the connections in a network and are widely applicable to a variety of physical, biological, and information systems. We are skipping out the first column of col_only so that it assigns the nodes (the circles in the plot) the actual Twitter handle as a label and not the numeric user ID, which is meaningless to humans. Chapter 10 Extensions. Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity. I've been skirting around the issue for a few blog posts, but now I think it's finally time to dive in to a full-blown social network analysis of my R Twitter dataset.
