addData(object, celdir = NULL, celfiles = "", celnames = NULL, project = NULL, verbose = TRUE)

Arguments

object

object of class DataTreeSet.

celdir

system directory containing the CEL-files for corresponding scheme.

celfiles

optional vector of CEL-files to be imported.

celnames

optional vector of names which should replace the CEL-file names.

project

optional class ProjectInfo.

verbose

logical, if TRUE print status information.

Value

A DataTreeSet object.

Examples

## get scheme and import subset of CEL-files from package
scheme.test3 <- root.scheme(paste(path.package("xps"),"schemes/SchemeTest3.root",sep="/"))
data.test3 <- import.data(scheme.test3,"tmp_test3",celdir=paste(path.package("xps"),"raw",sep="/"),
              celfiles=c("TestA1.CEL","TestB2.CEL"),verbose=FALSE)

unlist(treeNames(data.test3))

## add further subset of CEL-files
data.test3 <- addData(data.test3,celdir=paste(path.package("xps"),"raw",sep="/"),
              celfiles=c("TestA2.CEL","TestB1.CEL"),verbose=FALSE)

unlist(treeNames(data.test3))
