## Map between Manufacturer Identifiers and UniGene cluster identifiers

### Description

illuminaHumanv1UNIGENE is an R object that provides mappings between manufacturer identifiers and UniGene identifiers.

### Details

Each manufacturer identifier is mapped to a UniGene identifier. An `NA` is reported if the manufacturer identifier cannot be mapped to UniGene at this time.

A UniGene identifier represents a cluster of sequences of a gene. Using UniGene identifiers one can query the UniGene database for information about the sequences or the Entrez Gene database for information about the genes.

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

### Examples

            x <- illuminaHumanv1UNIGENE
            # Get the probe identifiers that are mapped to an UNIGENE ID
            mapped_probes <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_probes])
            if(length(xx) > 0) {
              # Get the UNIGENE for the first five probes
              xx[1:5]
              # Get the first one
              xx[[1]]
            }
