How to get the "articulation edges" in igraph?
I am trying to identify the edges between articulation points using igraph (and tidygraph) and its function articulation_points. In other words, I'm looking for the edges in my graph which if cut would split the graph in two. My first guess was that…

about how to put weight as distance in network analysis using tidygraph
I just performed a code to get a consistent graph using igraph and tidygraph.
In my example, the weight between A and C is just one. So the network graph from igraph package appropriately reflect weight as distance.
However,I think tidygraph failed…

Color a single node with tidygraph and ggraph
I have a tidy_igraph data network that I plot out. I want to however color a single node in the graph a distinct color from all others as it is the central point in the graph.
I did the following to make a tibble with a color column:

How to fix "function should not be called directly" error in tidygraph?
The problem is when I try to apply a dplyr::mutate function in order to get some measures of centrality to a List of network graphs, iterating thorugh them. I am working with tidygraph.
If I subsett one of the networks of the list, the code works…

Undirected network graph calculated by tidygraph shows more degree centrality than should be possible
I have a cleaned data set with 26 nodes. I am placing these 26 nodes in an undirected network graph using tidygraph, where I use the centrality_degree() function to calculate the centrality degree. However, when I graph the resulting network, my…

understanding a simple network chart
Consider this simple example
mynodes_alt <- tibble(id = c(1,2,4,5),
mygroup = c(2,2,3,3))
myedges_alt <- tibble(from = c(1,1,4),
to = c(4,2,3),
power = c(3,3,3))
tbl_graph(nodes = mynodes_alt,…

Computing the Everett-Valente Brokerage Score in TidyGraph
I want to compute the Everett-Valente Brokerage Score for each node in my directed network (Everett and Valente 2016). This score is based on betweenness centrality. Essentially, this controls for network size. The ability of a broker to control…
