strength {NetworkToolbox}

Node Strength

Description

Computes strength of each node in a network

Usage

strength(A, absolute = TRUE)

Arguments

A

An adjacency matrix of network data

absolute

Should network use absolute weights? Defaults to TRUE. Set to FALSE for signed weights

Value

A vector of strength values for each node in the network.

If directed network, returns a list containing:

inStrength

Strength of incoming edges (pointing to the node)

outStrength

Strength of outgoing edges (pointing away from the node)

relInf

Relative degree of incoming and outgoing edges. Positive values indicate more outgoing strength relative to incoming strength. Negative values indicate more incoming strength relative to outgoing strength

Examples

# Pearson's correlation only for CRAN checks
A <- TMFG(neoOpen, normal = FALSE)$A

str <- strength(A)

#Directed network
## Not run: 
dep <- depend(neoOpen)

Adep <- TMFG(dep, depend = TRUE)$A

str <- strength(Adep)

## End(Not run)
