signumAdjacencyFunction {WGCNA}

Hard-thresholding adjacency function

Description

This function transforms correlations or other measures of similarity into an unweighted network adjacency.

Usage

signumAdjacencyFunction(corMat, threshold)

Arguments

corMat

a matrix of correlations or other measures of similarity.

threshold

threshold for connecting nodes: all nodes whose corMat is above the threshold will be connected in the resulting network.

Value

An unweighted adjacency matrix of the same dimensions as the input corMat.
