Insights delivered by the course were great. However, I think it emphasizes too much the lattice and basic plot systems to the point it is redundant with functionality on ggplot. It should focus more on concepts and techniques for delivering richer and meaningful graphics using ggplot rather than talking that much about technicalities on the basic plot and lattice systems.Assignments were too basic and dont reflect all the concepts learned in the lessons e.g. clustering, which I think are of great interest for researchers.
