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:ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Wed Apr 5 10:55:25 2006
Package built: Wed Apr 5 11:19:57 2006
