## An annotation data file that maps Open Reading Frame (ORF) identifiers to textural descriptions of the corresponding genes

### Description

yeast2DESCRIPTION maps yeast ORF identifiers to descriptive information about genes corresponding to the ORF identifiers

### Details

This is an R object containing key and value pairs. Keys are ORF identifiers and values are the corresponding descriptions of genes. Values are vectors of length 1. Probe identifiers that can not be mapped to descriptive information are assigned a value NA.

Annotation based on data provided by: Yeast Genome ( ftp://genome-ftp.stanford.edu/pub/yeast/data_download ) on 2009-May02

### Examples

            x <- yeast2DESCRIPTION
            # Get the probe identifiers that are mapped to gene descriptions
            mapped_probes <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_probes])
            if(length(xx) > 0) {
              # Get the gene descriptions for the first five probes
              xx[1:5]
              # For the first probe
              xx[[1]]
            }
