Extract Raw Edge List from TNA Model

Description

Extract individual-level transition counts as an edge list from a tna object.

Usage

get_edge_list(x, by_individual = TRUE, drop_zeros = TRUE)

Arguments

x	A tna object created by tna::tna()
by_individual	Logical. If TRUE (default), returns edge list with individual IDs. If FALSE, aggregates across all individuals.
drop_zeros	Logical. If TRUE (default), excludes edges with zero count.

Value

A data frame with columns:

id

Individual identifier (only if by_individual = TRUE)

from

Source state label

to

Target state label

count

Number of transitions

Examples

Mod <- tna::tna(tna::group_regulation)

# Get edge list by individual
edges <- get_edge_list(Mod)
head(edges)

# Aggregate across individuals
agg_edges <- get_edge_list(Mod, by_individual = FALSE)
