hgu95av2NM {hgu95av2} | R Documentation |
This is an R environment (hash table like) object containing key and value pairs for the mappings between probe identifiers (key) and the RefSeq accession for a mRNA record (value). Keys can be accessed using ls(name of the environment) and values using get(key, name of the environment) or multiget(keys, name of the environment). Values may be vectors of length 1 or greater depending on whether a given probe id can be mapped to only one or more RefSeq accession for a mRNA record. NA is used for probe ids that can not be mapped to a RefSeq accession for a mRNA record at this time.
Mappings were based on data provided by LocusLink
