A tbl_graph is an igraph object, but enables the user to manipulate both the edges and nodes elements as if they were data frames also. Both sf and tidygraph are relatively new packages (first released on CRAN in 2016 and 2024, respectively).
Webbtidygraph. This package provides a tidy API for graph/network manipulation. While network data itself is not tidy, it can be envisioned as two tidy tables, one for node data and one for edge data. tidygraph provides a way to switch between the two tables and provides dplyr verbs for manipulating them. Furthermore it provides access to a lot of ... WebbThe centrality of a node measures the importance of node in the network. As the concept of importance is ill-defined and dependent on the network and the questions under consideration, many centrality measures exist. tidygraph provides a consistent set of wrappers for all the centrality measures implemented in igraph for use inside …
