Very useful, I considered myself quite an advanced R user, but this class raised the level, especially with the R as OOB part. Good investment if you are not a beginner.

It is a good course that forced me to understand the s3 and s4 object of R and have gained an appreciation of "methods belonging to functions not belonging to objects".

This course helped the programmer understand some OO concepts and many other features of R that I may not have encountered. Very good, and the final assignment was good. It was worth putting the extra time in to do it correctly.

I learned a lot and appreciate the continued learnings.

I wish the assignments could be a mix of teacher and peer graded.

I have taken several courses on Coursera and this was by far the worst. First the course contained no lectures. The authors had basically copied segments of their textbooks along with code samples as teaching material. I could have done better by simply reading the textbook myself without paying for the course. Finally the way the final assignment is graded is terrible. It is as if the course organizers have completely washed their hands of any responsibility. You have to grade three peers so that your assignment will get in line to be graded. But there is no time line and the process is completely arbitrary. Students have to actively seek others on the class forum to grade their assignment (they will return the favor ). I really expected more from a course offered by JHU.

Much of this course is well-constructed, well-communicated and clear. Sections from weeks 1-3 were attuned to my programming skill level and the material was communicated generally so that those with experience in other languages could also follow along easily. I had no technical problems with submitting assignments or quizzes and I found the assignments with swirl to be effective in reinforcing the material from the readings. My biggest criticism of this course is about Week 4's content and its respective part in the final assignment. The content in Week 4 concerns Object-Oriented programming and this material was really hard to absorb. It seemed to come out of left field and the readings did not feel as clear as they were in other sections. The readings essentially say "Here is what object-oriented programming allows you to do [create/manipulate classes and objects]" but then goes back on itself by recommending that you do not use object-oriented programming to create custom classes or data structures because the R community already knows what data structures they like. Personally, I had a lot of trouble understanding this content because it was so briefly explained. This did not help me by the time I had to complete the object-oriented programming portion of the final assignment. It is very clear from the class forums that other students have found that section of the assignment particularly difficult for years. Overall, this course was excellent in teaching functional programming principles and application, but the object-oriented section slightly spoiled my experience of the course.

It is a short and good R course. It goes right to the more advanced stuff. Even a long time user of R will learn new things. The final project is revised by the same students which in my opinion makes it more of a challenge. I've never wanted a homework to be as perfect as this one.

Great course. Challenging and I learn a lot of new techniques to improve my R skills.

The style of these courses is not engaging. This is self study, similar to getting a book and reading.

Excellent subject matter. 4 stars instead of 5 is only because there was no video. I love the videos in the other courses in this track, since I am an auditory learner.
