In your case, you can try the following in the console: install.packages("igraph", type = "binary") Using type = "binary" may give you a slightly older version of the package, but most of the time, that should not cause too many problems. If a parameter is not given in the command line, and the corresponding vertex/edge/graph attribute is also missing then the general igraph parameters handled by igraph_options are also checked. The pertaining pages in my textbook (Bruggeman 2008, pp. Take care. But in the meantime I’ve decided to build up anticipation for the great event by publishing a range of blog posts describing the central parts of ggraph: Layouts, Nodes, Edges, and Connections. If you don’t have a look to the network section that provides an introduction. The igraph library offers several built-in layouts, and a sample of them is presented here. Usually, algorithms try to minimize edge crossing and prevent overlap. Edges can have uniform length or not. Choose your layout using the layout argument. Type help (layout) to see all the possibilities. igraph now tries to select the optimal layout algorithm, when plotting a graph. This initial release, version 0.1, covers only some igraph functions, as I focused on the things that I need personally. There are several ways to create an Igraph object: ...
