Map between Manufacturer Identifiers and Entrez Gene

Description

mgug4104aENTREZID is an R environment that provides mappings between manufacturer identifiers and Entrez Gene identifiers.

Details

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/. Built: Source data downloaded from Entrez Gene on Mon Sep 25 22:08:18 2006

Package built: Mon Sep 25 22:25:30 2006

Examples

    # Convert the environment to a list
    xx <- as.list(mgug4104aENTREZID)
    # Remove probe identifiers that do not map to any ENTREZID
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # The ENTREZIDs for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
    }
