### Description

gahgu95eCHR is an R environment that provides mappings between a custom probeset identifier and the chromosome that contains the gene of interest.

### Examples

            # Convert to a list
            xx <- as.list(gahgu95eCHR)
            # Remove probe identifiers that do not map to any chromosome
            xx <- xx[!is.na(xx)]
            if(length(xx) > 0){
                # Get the chromosome number for the first five probes
                xx[1:5]
                # Get the first one
                xx[[1]]
            }
