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.
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!

Great introduction to the plotting libraries in R and visualization of data.
However the introduction to hierarchical clustering, and Principle component analysis was extremely vague.
The course content applies to R. The teachers focused on the programming language rather than the application of the existing graphs to explore data.

A nice introduction to the three plotting systems in R. The second part is devoted to clustering, but it is not detailed enough to be really useful.

Important and interesting stuff - but lots of it is repeated too much, which make it seem like 4 weeks is too much for the material.

I would have liked an assignment to focus on the clustering methods and I think dimension reduction was reviewed way too quick.

Course is good in general but "HIERACHICAL CLUSTERING" part is hard to understand and is not clear, should be explained more.

Good class - links and slides have not been updated recently. Frustrating to finish without the exact linkts to the data.

Good course, but the SWIRL exercises (and a few quiz questions) needed to be updated for the latest version of ggplot2.
創建者 Johnny C•
In general was good, but there were some lectures and exercises which were disorganized ("plots with colors")
創建者 Erkan E•
I wish there several comprehensive examples of exploring some real data as guided by the course instructors.
創建者 Mehrdad P•
The course was overall ok, but I wish discussions about k-means, PCA and SVD were divided into two courses.
創建者 Daniel P•
I've learned plotting in R. I expect to learn more in four weeks of "Data Science" specialization.
創建者 Stuart A•
Course hasn't been updated in a long time, some of the data needed for the projects has migrated.

The third and fourth week were a big leap in knowledge and not really well explained, for me.

Excercises are very good. But I believe lecture could be more interesting and easily taught.
創建者 Guy P•
It misses an assignment which will allow to practice the clustering skills.
創建者 Alex s•
It focus too much on the tools and a little bit on the analysis
創建者 Amit O•
faced many technical difficluties in pratcice exerices in swirl
創建者 Victor M C T•
The swirl labs failed, I never could load the "field" module.
創建者 Eduardo V K•
There seems to be some outdated info in several tests.
創建者 Rafael A•
First two weeks are too repetitive with other courses
創建者 Kevin F•
pretty brief and basic. no assessment on clustering.
創建者 Erwin V•
Interesting stuff, but not a lot of detail
創建者 Oscar P G P•
It's necessary for more examples!!!!

Absolutely No technical help, like insane amounts of homework for each week. People have jobs and businesses to run. Incredibly short duration. Like literally this should have been spread out several more weeks. I would have dropped the class but I can’t. It’s so difficult to get i to the first set of practice assignments and these several sets. Honestly, I am literally getting no help on it and probably won’t pass because I am missing the deadline. I finished 5 coursera courses working on them for 24 none stop. I’ve literally been at this class all day. Besides all the insane amounts of assignments there’s tons of videos to watch and uploads to do. Go buy some books or take another class unless you are unemployed or have nothing better to do.
