Very good course! It provide me the foundation in learning how to plot and interpret data. This will definitely strengthen my "R programming" to generate publication type figure for my genomics data!

This is the second course I have taken from Roger Peng and both were outstanding. I have a strong math background, but not much of a background in stats, but this course was very approachable for me.

Good course on plotting libraries and useful plots in R. Wished there was more coverage of ggplot and less on lattice, but overall a useful course.

It delves into many important topics. I would advice to explore the topics in much more depth on your own. Overall a good breadth of topics.

The course is useful with a lot of learning.
The second half needs more of improvement, I think the pace is quite fast compared to others.

Awesome course ! It reaches you the crux of exploration of data . Although the SVD section could have been more thorough and detailed.

Great introduction! I am eagerly awaiting the opportunity to apply clustering and dimension reduction on real data in future courses.

Very interesting and insightful course. I enjoyed it.
Assignment was okay, could have provided more challenge and depth though.

Very good course. I liked the clustering examples. They were a little bit detached from the rest, but they were also great.

great intro to the plotting system. could be better with a dimension reduction assignment or quiz. this is very important!

I would rate 5 if the course wasn´t so focused on graphic analysis. But, even Like that it´s a very good experience.

It was a lot of material in a short time frame, but I feel like I really have a good grasp of creating graphs in R.

More practical exercises using ggplot2 and clustering would be beneficial. Maybe need to be a 8 weeks module.

Quantitatively assignments were less with no assignment for Week 3, however, the swirl exercises were good

this course is more about creating chart for EDA, need more material for reading/interpreting the charts

Useful for learning how to make plots, but not too detailed. Further analysis would have been helpful.

Really good if you do not have any background in the field. But even if you do it is a great review

Some of the links in the lectures are out of date, the forums usually have an updated link though.

Exploratory data analysis is a very important skill and it is a very good course to learn it.

Best of your courses yet. Doesn't suffer from difficulty spikes when you hit the projects.

SVD could be explained a little better i think. I am still not exactly sure how it works.

great course...though I would have preferred less focus on cluster and k means analysis.

It is a good course but in my opinion it is basically support with the R swirl() guide

Was a little perplexed that we did not address clustering at all in the assignments.
