The tna package includes functionalities for finding
cliques of the transition network as well as discovering communities. We
begin by loading the package and the example data set
group_regulation.
library("tna")
data("group_regulation", package = "tna")We fit a TNA model to the data.
tna_model <- tna(group_regulation)
print(tna_model)

plot(tna_model)
Next, we apply several community finding algorithms to the model (see
?communities for more details), and plot the results for
the leading_eigen algorithm.
cd <- communities(tna_model)
plot(cd, method = "leading_eigen")
Cliques can be obtained with the cliques function. Here
we look for dyads and triads by setting size = 2 and
size = 3, respectively. Finally, we plot the results.
layout(matrix(1:4, ncol = 2, byrow = TRUE))
dyads <- cliques(tna_model, size = 2, threshold = 0.2)
triads <- cliques(tna_model, size = 3, threshold = 0.05)
plot(dyads, ask = FALSE)
plot(triads, ask = FALSE)
