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".

A bit too tough with not good enough teaching to truly understand the course

"Advanced" is not really accurate. "Intermediate" is a better description. I would have given 4 stars for content alone. The faux testing and peer grading at scale doesn't work well enough, so the certificate is not worth paying for. If you need a credential, enroll in real school. If you need a decent intro to intermediate programming topics in R, this is pretty good. The text for the course is excellent and worth purchasing. The programming exercises via swirl() fail at times, and peer grading as an assessment approach is not viable at scale.

I like this course as it offers some really practical instructions to programming in R, and I think it's a course that well complements the online book Advanced R written by Hadley Wickham, which focuses more on theories.

Swirl is confusing and it is too complicated to submit my work

Very knowledge and rigourous course, developed for comprehensive concept building.

I find that some of the course materials are not sufficient for the learners to understand the concept in R programming and complete the assignment. The course could be improved by including more examples and hands-on exercises.

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.
