This vignette showcases some basic usage of the tna
package. First we load the package that we will use for this
example.
We also load the group_regulation data available in the
package (see ?group_regulation for further information)
data("group_regulation", package = "tna")We build a TNA model using this data with the tna()
function .
tna_model <- tna(group_regulation)To visualize the model, we can use the standard plot()
function.
plot(
tna_model, cut = 0.2, minimum = 0.05,
edge.label.position = 0.8, edge.label.cex = 0.7
)
The initial state probabilities are
data.frame(`Initial prob.` = tna_model$inits, check.names = FALSE) |>
rownames_to_column("Action") |>
arrange(desc(`Initial prob.`)) |>
gt() |>
fmt_percent()| Action | Initial prob. |

| monitor | 14.40% |

The function centralities() can be used to compute
various centrality measures (see ?centralities for more
information). These measures can also be visualized with the
plot() function.
centrality_measures <- c("BetweennessRSP", "Closeness", "InStrength", "OutStrength")
cents_withoutloops <- centralities(
tna_model,
measures = centrality_measures,
loops = FALSE,
normalize = TRUE
)
plot(cents_withoutloops, ncol = 2, model = tna_model)
