Brilliant course. Loved Week 4 for OOP. This was really new for me and would love to have been able to see its application in real world examples to better cement the concepts.
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.

Great course content, but other than the 1-minute video it's all available online via bookdown.org. The course has been adandoned, which means that you can't get enough peer reviews to finish the course in a timely manner. This course is completely to blame for the end of my motivation to finish the specialization. I have done the other JHU R specializations (data science, visualization, tidyverse, executive) and they were great, but this one is just garbage. I guess I'll mentally switch to just auditing this material (aka, just read the book and do the quizzes but not worry about the assignments) to get through the courses and then drop it. Coursera has a lot of short courses/projects that are newer and will be a lot more fun than. This tired course really should just be archived or switched to an entirely independent course (i.e., no peer reviewed assignments).

"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.

If you're relatively new to R coding and coming straight from the first course (R Programming Environment), prepare to expect the same thing... Very easy activities and a lot of reading, and then an incredibly difficult final assignment which only a small portion of the reading actually prepares you for. Researching the methods/code necessary to do it is possible do get it done but I honestly feel that I haven't actually learnt how to do it... I've done it once and if you ask me to do something similar again, I'll struggle, again.

- There should be more in-depth discussions and examples in the course material, as well as more exercises to practice R programming.
- The principles of object-oriented programming (pp. 159-174 in the course material) are only superficially taught. What is explained in the course material is not enough to do the final exercise properly.
- The peer-review system does not allow to get any useful feedback in practice.

Since this course, the material seems to be not thorough. In fact, it is quite "too much" on talking, but lack of examples of codes and real problem solves. That makes the contents very abstract, and learners could be very confused when doing the assignments.

Very useless. It is the same as downloading one book and reading it in a day. No videos, no guidance, no coordination. DO NOT WASTE YOUR MONEY, I repeat. I reject taking this course.

This course is text-based, but the text is hard to read because of numerous missing space characters and widespread formatting issues. Please make it... tidy!..

Great gap between teaching and what is required to pass the course. Unnecessarily difficult.
The didactic material is not compelling.

Final assignment may not be reviewed for weeks. If you go on to capstone, issue could extent into months. Expect to use many external resources.

The assignments are not available. There are comments from 3 years ago about the assignments being difficult to find/start.

I could never submit my grade for the quiz. Waste me three days getting nothing from this class

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