## Map MGI gene accession numbers with manufacturer identifiers

### Description

mgu74aMGI is an R object that contains mappings between manufacturer identifiers and Jackson Laboratory MGI gene accession numbers.

### Details

This object is a simple mapping of manufacturer identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to MGI gene Accession Numbers.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Apr2

### Examples

        x <- mgu74aMGI
        # Get the manufacturer IDs that are mapped to an MGI ID
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the MGI IDs for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
        #For the reverse map MGI2EG:
        # Convert to a list
        xx <- as.list(mgu74aMGI2PROBE)
        if(length(xx) > 0){
           # Gets the manufacturer IDs for the first five MGI IDs
           xx[1:5]
           # Get the first one
           xx[[1]]
        }
