Map Ensembl gene accession numbers with manufacturer identifiers

Description

rgug4105aENSEMBL 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 <- rgug4105aENSEMBL
    # 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(rgug4105aENSEMBL2PROBE)
    if(length(xx) > 0){
       # Gets the manufacturer IDs for the first five Ensembl IDs
       xx[1:5]
       # Get the first one
       xx[[1]]
    }
