\name{GeneSelector-package} \alias{GeneSelector-package} \docType{package} \title{Stability and aggregation of ranked gene lists} \description{The term 'GeneSelector' refers to a filter selecting those genes which are consistently identified as differentially expressed using various statistical procedures. 'Selected' genes are those present at the top of the list in various featured ranking methods (currently 14). In addition, the stability of the findings can be taken into account in the final ranking by examining perturbed versions of the original data set, e.g. by leaving samples, swapping class labels, generating bootstrap replicates or adding noise.} \details{ \tabular{ll}{ Package: \tab GeneSelector\cr Type: \tab Package\cr Version: \tab 1.5.1\cr Date: \tab 2009-13-5\cr License: \tab GPL (version 2 or later) \cr } Important steps of the workflow: \describe{ \item{1.}{Generate a Gene Ranking with \link{RankingTstat}, \link{RankingFC}, \link{RankingWelchT}, \link{RankingWilcoxon}, \link{RankingBaldiLong}, \link{RankingFoxDimmic}, \link{RankingLimma}, \link{RankingEbam}, \link{RankingWilcEbam}, \link{RankingSam}, \link{RankingShrinkageT}, \link{RankingSoftthresholdT}, \link{RankingPermutation}} \item{2.}{Inspect the toplist using \code{toplist}.} \item{3.}{Prepare altered datasets using \link{GenerateFoldMatrix} or \link{GenerateBootMatrix}} \item{4.}{Get rankings for the altered datasets with \link{RepeatRanking}.} \item{5.}{Assess stability of rankings using \link{GetStabilityOverlap}, \link{GetStabilityDistance}, \link{GetStabilityUnion}.} \item{6.}{Aggregate different rankings with \link{AggregateSimple}, \link{AggregatePenalty}, \link{AggregateMC} or \link{AggregateSVD}.} \item{7.}{Inspect the similarity of methods visually using \link{HeatmapRankings}.} \item{8.}{Run the \link{GeneSelector}.} } } \author{Martin Slawski \email{ms@cs.uni-sb.de}, \cr Anne-Laure Boulesteix \email{boulesteix@ibe.med.uni-muenchen.de} Maintainer: Martin Slawski \email{ms@cs.uni-sb.de}. } \keyword{univar}
