calc_centrality: Compute Centrality for a Weighted/Unweighted Network

In lsaravia/EcoNetwork: Ecological network analyses including multiplex networks

Compute Centrality for a Weighted/Unweighted Network

Description

This function calculates the centrality of species in a network based on an adjacency matrix or igraph object using a specified centrality measure.

Usage

calc_centrality(A, centrality_func = eigen_centrality)

Arguments

A	An igraph object or an adjacency matrix. The values represent interaction strengths.
centrality_func	A function to compute centrality. Default is eigen_centrality. Other options: page_rank, betweenness, degree, etc.

Value

A list containing:

CentralityScores	A data frame with species names and their centrality scores.
Plot_Centrality	A ggplot object showing the top 10 species by centrality.

Examples

# Example usage with an adjacency matrix A
results <- calc_centrality(A, centrality_func = page_rank)
print(results$CentralityScores)
print(results$Plot_Centrality)
