Get cluster selection matrix

Given a matrix of feature selection indicator variables and a list of clusters of features, returns a matrix of cluster indicator variables.

Usage

getClusterSelMatrix(clusters, res)

Arguments

clusters

A named list where each entry is an integer vector of indices of features that are in a common cluster, as in the output of formatClusters. (The length of list clusters is equal to the number of clusters.) All identified clusters must be non-overlapping, and all features must appear in exactly one cluster (any unclustered features should be in their own "cluster" of size 1).

res

A binary integer matrix. esi, j = 1 if feature j was selected on subsample i and equals 0 otherwise, as in the output of getSelMatrix(). (That is, each row is a selected set.)

Value

A binary integer matrix with the same number of rows as res and length(clusters) columns. Entry i, j is 1 if at least one member of cluster j was selected on subsample i, and 0 otherwise.
