Exercise

Peaks vs background

Now it is time to compare the coverage distribution of peaks, blacklisted regions, and background. In this exercise, you will examine data from chromosome 5. The binned read counts for peaks, blacklisted regions, and background for this chromosome are available as peak_bins, bl_bins, and bkg_bins respectively. The score column contains the read counts.

It may take a moment to load all required data and R packages for this exercise. Please be patient.
