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.

The data used for training are too big to be processed on my computer....
It is a real burden for my laptop when I use Rstudio to view some big files.....

pretty good starter course. I liked 40 min Case Study video at the end. It was very helpful to watch the instructor do the analysis from start to finish.

I think this is a great course. I learned a lot about data plotting and some multivariate techniques for understanding underlaying patterns of the data.

Wonderful course with lot of graphical representation of the data. Dimensional reduction and Clustering analysis needs a bit more detailed explanation.

Very solid class in terms of R's base plotting system. I wish Coursera offered an advanced class focusing on ggplot2 and the wider world of dat viz.

This was a great course. I learned how to use several graphic systems within R, and to imagine how to make clear answers to questions using plots.

This was an important class because in future classes in the certification peer reviewed projects require some sort of exploratory data analysis.

Great Course. Lectures did diverge from Quizes and projects but still was good practice of looking at a set of data and reporting out from it.

Learned a great deal. Especially on clustering.
The second project could be a little more challenging; I overestimated the answers requested.
