## Map custom probeset IDs to gene start position

### Description

gahgu95cGENESTART is an R environment that provides mappings between a custom probeset identifier and the base pair starting position of gene onto corresponding chromosome.

### Details

Each identifier maps to a gene start position. If the gene start position is unknown, the vector will contain an `NA`.

Mappings were based on data provided by:

### Examples

            # Convert to a list
            xx <- as.list(gahgu95cGENESTART)
            # Remove probe identifiers that do not map to any gene start position
            xx <- xx[!is.na(xx)]
            if(length(xx) > 0){
                # Get the base pair number for gene start position for the first five probes
                xx[1:5]
                # Get the first one
                xx[[1]]
            }
