centrality_harmonic: Harmonic Centrality

Description

Sum of inverse shortest path distances to all other nodes. Unlike closeness, harmonic centrality handles disconnected graphs naturally (unreachable nodes contribute 0 instead of making the measure undefined).

Usage

centrality_harmonic(x, mode = "all", ...)
centrality_inharmonic(x, ...)
centrality_outharmonic(x, ...)

Value

Named numeric vector of harmonic centrality 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).

See Also

centrality for computing multiple measures at once, centrality_closeness for the traditional variant.

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), 3, 3)
rownames(adj) <- colnames(adj) <- c("A", "B", "C")
centrality_harmonic(adj)
