## Map Between Manufacturer IDs and Genes

### Description

m20kcodGENENAME is an R environment 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:

### Examples

         # Convert to a list
         xx <- as.list(m20kcodGENENAME)
         # 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 identifiers
             xx[1:5]
             # Get the first one
             xx[[1]]
         }
