preprocessMatrices: Remove unnecessary entries from matrices

Description

Remove patients (rows) which are not in both matrices from patMutMatrix and patOutMatrix. Remove mutations (columns) from patMutMatrix if they are not a row of influenceGraph. Remove expressions (columns) from patOutMatrix if they are not a column of influenceGraph.

Usage

preprocessMatrices(patMutMatrix, patOutMatrix, influenceGraph)

Arguments

patMutMatrix

Patient Mutation Matrix

patOutMatrix

Patient Outlier Matrix

influenceGraph

Influence Graph Matrix

Value

1

Reduced version of Patient Mutation Matrix

2

Reduced version of Patient Expression(Outlier) Matrix

3

Influence Graph Matrix

Examples

data(samplePatientMutationMatrix)
data(samplePatientOutlierMatrix)
data(sampleInfluenceGraph)
tmp = preprocessMatrices(samplePatientMutationMatrix, samplePatientOutlierMatrix, 
sampleInfluenceGraph)

smallerPatientMutationMatrix = tmp[[1]]
smallerPatientOutlierMatrix = tmp[[2]]
influenceGraph = tmp[[3]]
