SelectionProportions: Selection/co-membership proportions

Description

Extracts selection proportions (for stability selection) or co-membership proportions (for consensus clustering).

Usage

SelectionProportions(stability, argmax_id = NULL)
ConsensusMatrix(stability, argmax_id = NULL)

Value

A vector or matrix of proportions.

Arguments

stability

output of VariableSelection, GraphicalModel, BiSelection, or Clustering.

argmax_id

optional indices of hyper-parameters. If argmax_id=NULL, the calibrated hyper-parameters are used.
