attachUnitNames-methods: Attach/Remove Unit Names

Description

Attach/remove unit names, i.e. the Affymetrix probeset IDs to/from SchemeTreeSet or to slot scheme of DataTreeSet.

Usage

attachUnitNames(object, treetype = "idx")

removeUnitNames(object)

Arguments

object

Object of class "SchemeTreeSet" or "DataTreeSet".

treetype

the unit tree type, i.e. ‘idx’ or ‘pbs’.

Value

A DataTreeSet object or SchemeTreeSet.

Details

attachUnitNames exports “UnitName” from unit tree of ROOT scheme file and and saves it as data.frame in slot unitname.

removeUnitNames removes unitname from slot unitname and replaces data.frame unitname with an empty data.frame of dim(0,0).

For treetype="idx" the internal “UNIT_ID” will be mapped to the Affymetrix probeset IDs of the expression arrays or to the transcript_cluster_ids of the exon arrays, respectively, as “UnitName”.

For treetype="pbs" the internal “UNIT_ID” will be mapped to the Affymetrix probeset_ids of the exon arrays as “UnitName”.

Examples

## first, load ROOT scheme file
scheme.test3 <- root.scheme(paste(path.package("xps"),"schemes/SchemeTest3.root",sep="/"))

## attach unitname
scheme.test3 <- attachUnitNames(scheme.test3)

## get data.frame
unitnames <- unitNames(scheme.test3)
head(unitnames)

## remove unitname
scheme.test3 <- removeUnitNames(scheme.test3)

rm(scheme.test3)
