     Object of class 'data.frame'. GFF is a file format for annotating
     genomes, see <insert the URL to the documentation page for GFF at
     Sanger here>. The format is essentially a rectangular table, and
     here it is represented as a data frame.

     Two GFF files were downloaded: 'saccharomyces_cerevisiae.gff' from
     'ftp://genome-ftp.stanford.edu/pub/yeast/data_download/chromosomal
     _feature' on 7 Aug 2005, 18:16 BST, and
     'IGR_v24.2.p001.allowoverlap.GFF' from
     'http://jura.wi.mit.edu/fraenkel/download/release_v24/GFF' upon
     suggestion from the SGD curators on 30 Aug 2005. (Future versions
     of SGD's GFF files are likely to include the latter as well). They
     were parsed, combined and written into the 'gff' data.frame with
     the script 'makeProbeAnno.R' in the 'inst/scripts' directory of
     this package.
