## Map ORF IDs to Chromosomes

### Description

org.Sc.sgdCHR is an R object that provides mappings between ORF identifiers and the chromosome that contains the gene of interest.

### Details

Each ORF identifier maps to a vector of a chromosome.

Mappings were based on data provided by: Yeast Genome ( ftp://genome-ftp.stanford.edu/pub/yeast/data_download ) on 2008-Sep06

### Examples

            x <- org.Sc.sgdCHR
            # Get the ORF identifiers that are mapped to a chromosome
            mapped_genes <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_genes])
            if(length(xx) > 0) {
              # Get the CHR for the first five genes
              xx[1:5]
              # Get the first one
              xx[[1]]
            }
