Discovering the Yeast genome

Let's continue to explore the yeast genome using the package BSgenome.Scerevisiae.UCSC.sacCer3 which is already installed for you.

As with other data in R, we can use head() and tail() to explore the yeastGenome object. We can also subset the genome by chromosome by using $ as follows: object_name$chromosome_name. If you need the names of the chromosomes use the names() function.

Another nifty function is nchar(), used to count the number of characters in a sequence.
