## Map between Manufacturer IDs and Genes

### Description

hgu133plus2GENENAME is an R object that maps manufacturer identifiers to the corresponding gene name.

### Details

Each manufacturer identifier maps to a named vector containing the gene name. The vector name corresponds to the manufacturer identifier. If the gene name is unknown, the vector will contain an `NA`.

Gene names currently include both the official (validated by a nomenclature committee) and preferred names (interim selected for display) for genes. Efforts are being made to differentiate the two by adding a name to the vector.

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

### Examples

            x <- hgu133plus2GENENAME
            # Get the probe identifiers that are mapped to a gene name
            mapped_probes <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_probes])
            if(length(xx) > 0) {
              # Get the GENENAME for the first five probes
              xx[1:5]
              # Get the first one
              xx[[1]]
            }
