## Map Between Manufacturer IDs and Genes

### Description

hgu133bGENENAME is an R environment that maps manufacturer identifiers to the corresponding gene name.

### Details

Each manufacturer id maps to a named vector containing the gene name. The vector name corresponds to the manufacturer id. 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:http://gopher5/compbio/annotationSourceData/ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Tue May 17 13:06:00 2005

### Examples

         # Convert to a list
         xx <- as.list(hgu133bGENENAME)
         # Remove probes that do not map to any GENENAME
         xx <- xx[!is.na(xx)]
         if(length(xx) > 0){
             # Gets the gene names for the first five probe ids
             xx[1:5]
             # Get the first one
             xx[[1]]
         }
