In lumi: BeadArray Specific Methods for Illumina Methylation and Expression Microarrays

Description

Get the mapping information (including mapping quality information) of nuIDs to the most recent RefSeq release. These information was kept in the IDMapping libraries.

Usage

getNuIDMappingInfo(nuID = NULL, lib.mapping)

Arguments

nuID	a vector of nuIDs. If it is NULL, all mappings will be returned.
lib.mapping	the ID mapping library

Details

The function basically return the nuID mapping information kept in the "nuID\_MappingInfo" table of IDMapping libraries (lumiHumanIDMapping, lumiMouseIDMapping, lumiRatIDMapping). For more details of nuID mapping, please refer to the help of corresponding IDMapping library.
