## Map between Manufacturer Identifiers and Entrez Gene

### Description

hgug4112aLOCUSID is an R environment that provides mappings between manufacturer ids and Entrez Gene ids.

### Details

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 Sun Mar 26 00:47:35 2006

Package built: Sun Mar 26 01:13:37 2006

### Examples

        # Convert the environment to a list
        xx <- as.list(hgug4112aLOCUSID)
        # Remove probe ids that do not map to any LOCUSID
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # The LOCUSIDs for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
