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".

The class does not cover all material needed for the final assignment in depth enough. I had to do extensive research outside of the class materials to be able to complete the assignment. I learned a lot, but I shouldn't have to do too much outside work to complete assignments for a class I paid for.

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.
