Hi I would like to use the genefinder command with correlation as dist metric rather than euclidean. The command looks something like: gf<-genefinder(eset, c("210354_at","219179_at"), numResults=25, scale="zscore", method="euclidean") Nms1<-geneNames(eset)[gf$"219179_at"$indices] X<-multiget(Nms1,env=hgu133aSYMBOL) X Regards Anthony -- ______________________________________________ Anthony Bosco - PhD Student Institute for Child Health Research (Company Limited by Guarantee ACN 009 278 755) Subiaco, Western Australia, 6008 Ph 61 8 9489 , Fax 61 8 9489 7700 email anthonyb@ichr.uwa.edu.au
