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.

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

PCA and SVD are not included in any assignment, it will be great if they are in the future

Plotting is very usefulIt would be great to have a step by step breakdown of PCA and SVD.

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.

SVD & PCA videos need improvement in terms of background knowledge and understanding

You should give more datasets for independent practice! Something we can play with.

ggplot should have been given more emphasis. It warrants a course on its own!

swirl is very used in this course. It is one of the best tools to learn R
