## Map Manufacturer IDs to Chromosomal Location

### Description

hu6800CHRLOC is an R environment that maps manufacturer identifiers to the starting position of the gene. The position of a gene is measured as the number of base pairs.

### Details

Each manufacturer identifier maps to a named vector of chromosomal locations, where the name indicates the chromosome. Due to inconsistencies that may exist at the time the environment was built, these vectors may contain more than one chromosome and/or location. If the chromosomal location is unknown, the vector will contain an `NA`.

Chromosomal locations on both the sense and antisense strands are measured as the number of base pairs from the p (5' end of the sense strand) to q (3' end of the sense strand) arms. Chromosomal locations on the antisense strand have a leading "-" sign (e. g. -1234567).

Mappings were based on data provided by:

### Examples

        # Covert to a list
        xx <- as.list(hu6800CHRLOC)
        # Remove probe identifiers that do not map to any CHRLOC
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # Gets the location for the first five probes
            xx[1:5]
            # Gets the first one
            xx[[1]]
        }
