## Map Ensembl gene accession numbers with manufacturer identifiers

### Description

POCRCannotationENSEMBL is an R object that contains mappings between manufacturer identifiers and Ensembl 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 Ensembl 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 <- POCRCannotationENSEMBL
        # Get the manufacturer IDs that are mapped to an Ensembl ID
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the Ensembl IDs for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
        #For the reverse map ENSEMBL2EG:
        # Convert to a list
        xx <- as.list(POCRCannotationENSEMBL2PROBE)
        if(length(xx) > 0){
           # Gets the manufacturer IDs for the first five Ensembl IDs
           xx[1:5]
           # Get the first one
           xx[[1]]
        }
