## Map Manufacturer IDs to Chromosomes

### Description

ath1121501CHR is an R environment that provides mappings between a manufacturer identifier and the chromosome that contains the gene of interest.

### Details

Each manufacturer identifier maps to a vector of chromosomes. Due to inconsistencies that may exist at the time the environment was built, the vector may contain more than one chromosome (e.g., the identifier may map to more than one chromosome). If the chromosomal location is unknown, the vector will contain an `NA`.

Mappings were based on data provided by:

### Examples

            # Convert to a list
            xx <- as.list(ath1121501CHR)
            # Remove probe identifiers that do not map to any CHRLOC
            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]]
            }
