An edge list of observed interactions between 34 students during collaborative learning sessions. Each row represents one observed interaction between two students. The same pair may appear multiple times, reflecting repeated interactions.
Format
A data frame with 389 rows and 2 columns:
- from
Character. Anonymized two-letter student code (e.g., "Ac", "Bd")
- to
Character. Anonymized two-letter student code (e.g., "Ce", "Df")
Value
A data frame with 389 rows and 2 columns:
- from
Character. Anonymized two-letter student code.
- to
Character. Anonymized two-letter student code.
Details
The dataset includes self-loops (34 rows where from == to).
These can be removed with subset(student_interactions, from != to).
The 389 rows contain 226 distinct ordered pairs. Because interactions
repeat, the edge list forms a multigraph when loaded into igraph with
igraph::graph_from_data_frame().
Examples
as_cograph(student_interactions)
#> Cograph network: 34 nodes, 389 edges ( directed )
#> Source: edgelist
#> Data: data.frame (389 x 2)
#> Nodes (34): Ac, Ad, Fi, Ik, Vx, Rt, ... +28 more
#> Weights: 1 (all equal)
#> Layout: none
#> Use as.data.frame() for the edge table, as.data.frame(what = "nodes") for the nodes.
