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 final project did not require use of the material in the course beyond the first week and a half. I did not take any quizzes or otherwise have my knowledge tested on the material in the second half of the course.
par Rohith J
•Course content and assignments were difficult to follow. Loads of statistical content along with high-level R content means it was probably the toughest of the 4 I have taken so far in the Coursetrack.

•some swirl tests (4,5) don't work because of parameter method in qplot function. This parameter is not realy existed in this function now
par Freddie K
•Quite repetitious in covering basic graphing, and very shallow in regards of clustering, SVD and PCA.
par Tamaz L
•Very unprofessional, compared to other courses. It wasn't well organized.
par Desmond W
•About plotting in R. Not about generating real insights from EDA.
par Esther L
•Too weak regarding the clustering methods, very disappointed.

•didnt get much useful-- a whole "course" on plotting? meh.
par Vineet P
•Not upto expectations
par Michal K
•too superficial
par Piyush V
•Veyr boring

•I can't help but feel lied to. The FAQ for the specialization says the following: "We also suggest a working knowledge of mathematics up to algebra (neither calculus or linear algebra are required). " If no linear algebra background is required, then why do you assume that I know what a singular value decomposition is? Or principal components analysis? Terrible course.
par Christy P
•How can you have a course on Graphic Devices and not show one screen shot of a graphic or open R to show how to perform the ideas around this topic?
par Nicholas
•NEEEEEED TO EDIT MY PEER REVIEW FROM OTHERS
par Carsten J
•Material is to basic for an entire course.
par omar k
•limited and monotonous explanation
