In comparison with the first course, it was not so useful. The main reason in my mind is that there was no video.

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

This courses touches many interesing aspects about R programming but I did not like the structure , it does not seem to me that it adequates its difficulty coming from "The R programming enviornment".

Also I miss some swirl lessons for many of the readings from the book. There are not too many help from the mentors and the peer assigment in week 4 took me too much time and had to consult a lot of external resources. Readings in general are OK but too simple.

I have learnt many things but

The topics are good, but very little practice of creating classes until the final quiz, which expects you to understand it completely without having done any practice.

The Object oriented programming section did not provide an adequate amount of support for the assignment, compared to any of the other parts of the Course.

just links to a webpage... no support from the mentors no support form coursera... you can use your money more wisely..

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

difference was observed in final test and study material.

I was really disappointed in this course. Most (if not all) of the materials are copy / pasted from a book that is free online. While I can get past that, my biggest concern is the actual content and assessments.

The content covers really basic examples and explains the concepts superficially, then the assessments expect students to be able to apply those concepts to a higher-level problem. As a university professor (and a cognitive psychologist), I completely understand the purpose of having students apply the information they've learned in a novel situation or environment. BUT that is only useful if the student has foundational knowledge on which to build. This course is akin to reading a dictionary definition, then being expected to apply it to an intermediate-level problem that resembles nothing you've ever seen. In the case of this course, the majority of my (and others', based on the forum discussions) learning was outside of the course. I have a hard time believing that any of which I "learned" searching for answers is going to stick with me long term.

The final assessment does not lay out the requirements (on which you are later graded). There are multiple things you get points for having in the code--even though a handful of them are not required for fully capable code--that are not specified as requirements in the final assignment. This isn't so much about the course per se, but something I find irritating and an impediment to learning in general.

That being said, I found the swirl assignments useful and engaging, and the course content was fairly easy to get through.

Overall I think more relevant examples would be useful, as would a more-detailed explanation of some of the concepts. If you take this course, I'd prepare to spend at LEAST a few days at the end of the course scouring the web for more relevant and detailed answers to your questions that were brushed over, if even addressed at all, in the course materials. It'd be better to go look for examples while you're learning instead of waiting until the assessment, though (if you're interested in decreasing the tax of the final assignment and increasing the potential for long-term learning).

"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.

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.

Great gap between teaching and what is required to pass the course. Unnecessarily difficult.

The didactic material is not compelling.

Not recommended.

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.

What is the point of this course? Without any lectures, I'm not getting anything other than I could from just buying a book. I'm out.

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
