The data are from an experiment that used Affymetrix Scerevisiaetiling chips from 2004, which where custom-made for the Stanford Genome Center. The chips tile the complete genome of S. cerevisiae in steps of 8 bases, separately for each strand of each chromosome. The two tiles for one chromosome (Watson and Crick strands) are offset by 4 bases.

An environment with probe mapping information for the Scerevisiae tiling array
The environment contains probe mapping information for the Affymetrix Scerevisiaetiling chip from 2004, which was custom-made for the Stanford Genome Center. The chips tile the complete genome of S. cerevisiae in steps of 8 bases, separately for each strand of each chromosome. The two tiles for one chromosome (Watson and Crick strands) are offset by 4 bases.
yeastFeatures
(Package: davidTiling) :
A data.frame with metadata about the features in SGD GFF files
The rows of the data frame correspond to feature categories, such as "gene", "CDS", "telomere". The column isTranscribed is a logical vector that denotes whether this feature category is considered to be transcribable.
