GenomicRanges accessors
In the previous exercise, you created a GRanges object from a data frame containing the basic information. You will discover that GRanges can store much more!
Use the accessor method to explore the GRanges object, myGR. You can extract characteristics from a GRanges object such as chromosome names, the number of sequences, the names of each sequence, information about strand, score, length, and more.
The following are basic accessors for GRanges:
seqnames(gr)
ranges(gr)
mcols(gr)
genome(gr)
seqinfo(gr)
For a complete list of accessors, you can check methods(class = "GRanges").
