Social network analysis (SNA) is the methodical analysis of social networks. Social network analysis views social relationships in terms of network theory, consisting of nodes (representing individual actors within the network) and ties (which represent relationships between the individuals, such as friendship, kinship, organizational position, sexual relationships, etc.)

Matrix heatmap in ggplot not consistent in upper and lower triangles
For some reason, this symmetrized matrix is plotting with either no data in the lower triangle of the heatmap or just a little as shown in the below figure. I can't figure out why it's happening. Any guesses? I've shared the first 100 rows of the…

I'm missing the ties for the other nodes in my network and I'm unsure why, any help would be much appreciated
My code is the following:
D_igraph <- graph_from_data_frame(d = edges, vertices = nodes, directed = FALSE)
as.numeric(Strength1)
set.graph.attribute(D_igraph, "Strength_of_tie", Strength1)

Every node in graph must have only 6 neighbors using R
I have a random graph of 10 nodes (possibly there can be more than 1000 nodes). I have write the following code.
g <- erdos.renyi.game(10,1,type = "gnp",directed = FALSE)
degree(g)
[1] 9 9 9 9 9 9 9 9 9 9
The network diagram is as follows.

How to fix the error in QAP test in SNA: Error in fun(dat, ...) : unused arguments
I would like to compare three networks with the same number of nodes. The three networks G1,G2 & G3 have been created using iGraph, and I have transferred them into network objects, which should be recognizable by SNA. However, when I tried to do a…

Importing edges to networkx library in Python
I am working on a social network analysis problem where I have a directed graph. I get an issue when I import the edges to my graph file, which for some reason makes it undirected, making it impossible to measure centralities such as in/out degree…

Networkx: Raising the labels above the node using position
I am very new to networkx (just started today!):
I am using these two links and replicating:
This is for creating the network
and This is for how I tried adjusting the label positions
So mine looks like this:
layout =…

Keeping Vertex Names when Converting to Edgelist in R
I am trying to convert a sociomatrix (using the sna package in r) into an edgelist, but keeping the vertex names. Unfortunately, I seem to be at a dead end.
For context, I'm using the sna package because I need to symmetrize the data, which I am…

How to convert dataframe with dummy variables into adjacency matrix?
I have a dataframe with multiple dummy variables.
df <- data.frame(A=c(1,0,1,0,1),B=c(1,1,1,0,0),C=c(0,1,0,1,1))
Acutually, the number "1" in each row represent the occurrence of varables, thus the dataframe is something like co-occurance…

Linear Threshold Model in R with igraph
I'm trying to implement a function in R that takes a graph object and with two "opinions" present on the same graph, starting at random points, I should study the diffusion patterns. There is a stubbornness (alpha) parameter between [0, 1], and for…

accessing nodes by name/id in the network package
In the network and sna packages, is there a way to ensure that you reliably access nodes by an arbitrary id/name, and return output using this id/name? It appears that, even if vertex names are explicitly assigned, the packages default to using 1:n…
