| mouse430a2LOCUSID {mouse430a2} | R Documentation |
mouse430a2LOCUSID is an R environment that provides mappings between manufacturer ids and Entrez Gene ids.
Each manufacturer id is mapped to a vector of Entrez Gene ids. An
NA is assigned to those manufacturer ids that can not be mapped
to an Entrez Gene id at this time.
If a given manufacturer id can be mapped to different Entrez Gene ids from various sources, we attempt to select the common ids. If a concensus cannot be determined, we select the smallest id.
Mappings were based on data provided by:
Entrez Gene:http://gopher5/compbio/annotationSourceData/ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Tue May 17 17:29:05 2005
Package built: Tue May 17 17:35:52 2005
