SWAP.PlotKTSP.Votes: Plots a heatmap of k-TSP votes.

In marchion/switchBox: Utilities to train and validate classifiers based on pair switching using the K-Top-Scoring-Pair (KTSP) algorithm

Description

Given a k-TSP classifer and a matrix of data, plots a heatmap of the votes of the pairs computed on the given data.

Usage

SWAP.PlotKTSP.Votes(classifier, inputMat, 
  Groups=NULL, CombineFunc, ...)

Arguments

classifier	is a k-TSP classifier produced by SWAP.KTSP.Train.
inputMat	is a matrix of data with rows being the features (such as gene names, if the matrix if gene expression data) and columns being the samples.
Groups	is a factor or a vector providing the phenotype class each sample belongs to. It should correspond to the order of samples given by the columns of inputMat. These phenotype labels will be added to the x-axis of the heatmap.
CombineFunc	is a function corresponding to the CombineFunc argument of the SWAP.KTSP.Classify function.

Value

Produces a heatmap where the color indicates a vote of 1 or 0 for a given sample by a top scoring pair.
