centralityPlot：An error has occurred in node Strength. #67

Closed yazawaninico00000 closed 1 year ago

I set up a simple network as follows： library(igraph) library(qgraph) g <- graph_from_literal(1-2, 1-3, 2-3, 2-4, 3-5, 4-5,4-6, 4-7, 5-6, 6-7)

However, the following problems occur when I want to use centralityPlot

centralityPlot(g, scale = "relative", include ="Degree") #This code runs normally. centralityPlot(g, scale = "relative", include ="Strength") # This code cannot run, and an error is reported：Error in combine_vars().....

Then I tried to use strength (g) to get the strength of the nodes. strength(g) This code outputs the strength of each node. I want to know why centralityPlot (g, scale="relative", include="Strength") reports error. I'm very grateful for some advice.

Hi! Node strength is simply called degree in the case of an unweighted graph. So the code you have with degree already works.
