agGENENAME {ag} | R Documentation |
agGENENAME is an R environment that maps manufacturer identifiers to the corresponding gene name.
Each manufacturer identifier maps to a named vector containing the gene
name. The vector name corresponds to the manufacturer identifier. If the gene
name is unknown, the vector will contain an NA
.
Gene names currently include both the official (validated by a nomenclature committee) and preferred names (interim selected for display) for genes. Efforts are being made to differentiate the two by adding a name to the vector.
Mappings were based on data provided by:
