centrality_pagerank: PageRank Centrality

Description

Random walk centrality measuring node importance. Simulates a random walker that follows edges with probability damping and jumps to a random node with probability 1 - damping.

Usage

centrality_pagerank(x, damping = 0.85, personalized = NULL, ...)

Value

Named numeric vector of PageRank values.

Arguments

x

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

damping

Damping factor (probability of following an edge). Default 0.85.

personalized

Named numeric vector for personalized PageRank. Values should sum to 1. Default NULL (uniform).

...

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

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), 3, 3)
rownames(adj) <- colnames(adj) <- c("A", "B", "C")
centrality_pagerank(adj)
centrality_pagerank(adj, damping = 0.9)
