rgug4130aUNIGENE {rgug4130a} | R Documentation |
rgug4130aUNIGENE is an R environment that provides mappings between manufacturer ids and UniGene ids.
Each manufacturer id is mapped to a UniGene id. An NA
is
reported if the manufacturer id cannot be mapped to UniGene at this time.
A UniGene id represents a cluster of sequences of a gene. Using UniGene ids one can query the UniGene database for information about the sequences or the LocusLink database for information about the genes.
Mappings were based on data provided by:
