## Map between Manufacturer Identifiers and Entrez Gene

### Description

hguatlas13kENTREZID 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 17:35:47 2006

Package built: Mon Sep 25 17:58:29 2006

### Examples

        # Convert the environment to a list
        xx <- as.list(hguatlas13kENTREZID)
        # 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]]
        }
