hu35ksubbENTREZID {hu35ksubb.db} | R Documentation |
hu35ksubbENTREZID is an R object that provides mappings between manufacturer identifiers and Entrez Gene identifiers.
Each manufacturer identifier is mapped to a vector of Entrez Gene identifiers. An
NA
is assigned to those manufacturer identifiers that can not be mapped
to an Entrez Gene identifier at this time.
If a given manufacturer identifier can be mapped to different Entrez Gene identifiers from various sources, we attempt to select the common identifiers. If a concensus cannot be determined, we select the smallest identifier.
Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Apr2
