centrality_lac: Local Average Connectivity (LAC)

Description

Average degree of neighbors within the neighborhood subgraph. Measures how interconnected a node's neighbors are. Proposed by Li et al. (2011) for identifying essential proteins in PPI networks.

Usage

centrality_lac(x, mode = "all", ...)

Value

Named numeric vector of LAC values.

Arguments

x

Network input (matrix, igraph, network, cograph_network, tna object).

mode

For directed networks: "all" (default), "in", or "out".

...

Additional arguments passed to centrality (e.g., normalized, weighted, directed).
