hu6800ACCNUM {hu6800} | R Documentation |
hu6800ACCNUM mappes probe identifiers and manufacturer (or user) provided public data repository identifiers that are used to map probe ids to Locuslink ids and thus other annotation data.
This is an environment object with key and value pairs. Keys are probe ids and values are manufacturer (user) provided ids are values. Values are vectors of length 1 with NAs assigned to probe ids that are not mapped to any public ids.
Often the values are GenBank accession numbers but sometimes can be UniGene ids, RefSeq ids, or Image clone ids.
