In DavisWeaver/crosstalkr: Analysis of Graph-Structured Data with a Focus on Protein-Protein Interaction Networks

Function to normalize adjacency matrix by dividing each value by the colsum.

Description

Function to normalize adjacency matrix by dividing each value by the colsum.

Usage

norm_colsum(w)

Arguments

w	The adjacency matrix of a given graph in sparse format - dgCMatrix

Value

input matrix, normalized by column sums

Examples

# 1) Normalize by column sum on a simple matrix
v1 = (c(1,1,1,0))
v2 = c(0,0,0,1)
v3 = c(1,1,1,0)
v4 = c(0,0,0,1)
w = matrix(data = c(v1,v2,v3,v4), ncol = 4, nrow = 4)
norm_colsum(w)
