In taoshengxu/CancerSubtypes: Cancer subtypes identification, validation and visualization based on multiple genomic data sets

Description

This is the affinity Matrix function extracted from SNFtool package. Computes affinity matrix from a generic distance matrix

Usage

affinityMatrix(Diff, K = 20, sigma = 0.5)

Arguments

Diff	Distance matrix
K	Number of nearest neighbors
sigma	Variance for local model

Value

Returns an affinity matrix that represents the neighborhood graph of the data points.

Examples

data(miRNAExp)
Dist1=dist2(t(miRNAExp),t(miRNAExp))
W1 = affinityMatrix(Dist1, 20, 0.5)
