Very Very Rigorous Course for a beginner on R language and because of its nature, after completing just one course, I feel like I have gained a lot of knowledge and also familiarity with R language.
A very good course to read and get the valuable content of R language. This is for the students who want to learn and practice the basic and some intermediate concepts of data manipulation.

You can learn most of it through the package swirl but the quiz at the end was a rewarding challenge that gave good practice. Would make it much better if it had video tutorials however

This is a fairly good course.The interactive R environment is a little rigid and acknowledges correct answers only when certain specific codes are used but all in all .its good

This is a refresher course for someone who already knows R. For anyone starting to learn R and Data Science, Data Science Specialization is a good curriculum to start with.

The instructors did nothing. They did not even respond to a single question through the entirety of the course. The information in the readings was helpful though.

If I didn't already have experience in R, and with tidyR in particular, I'm not sure this course would have been that helpful. As it was, it was a good review.
por Hans H•
One must have some R knowledge prior to take this course. I would recommend to take the other R programming course from the Data Science track before.

The use of swirl proved to be confusing to do week 2 test. I had to read the comment threads to figure out which subjects were needed for the quiz.
por KEVIN A F•
The course difficulty abruptly increased in the last week.Especially with the last quiz. A swirl exercise before the quiz would have been helpful.
por Daniel V•
Quick and easy introduction to R. Doesn't go into any depth, no videos and not very challenging assignments. Would not recommend.

Wrong tutorial on swirl that obliges you to follow the course twice to get the code for the quix and to take the points to go on
por Harsh D•
Less practice items in this course. Majority is theory. Would have preferred if it had a some more practice material.
por Nate W•
low production value at times, frustrating errors in the course data and instructions, but got me there in the end
por KEVIN E A C•
It was very dificul, i think yoou need to improve the example you give the the students and be more interactive
por Feng J•
The problem set is well-designed but the prompt and the wording could be misleading for non-native speakers.
por Andisheh P•
The final assignment is suddenly much more difficult than the rest of the course, otherwise a good course
por Haoyu Z•
The instruction from the first three weeks does not sufficiently prepare me for the final project.
por Nick B•
There HAS to be mentors/instructors around to assist with syntax questions during this process.
por Vrushali C•
some assignment questions are not from the lessons. please solve this issue .
por George E C•
Good course, but in serious need of updating and proofreading.
por Saif A K•
good course ,, but alot of readings :(
por Jan K•
A little too easy for the certificate.
por Luca B•
It was n't so easy

This course has some useful information, but it is far from polished, and it is unclear who the class is truly designed for. The readings have a number of formatting issue and typos. I was disappointed that this class did not utilize lecture videos or practice exercises. There is not enough opportunity to reinforce the material through practice, which turns the assessments into abrupt roadblocks. If I wanted to spend most of my time just reading about R, I could have bought a book instead. Compared to other courses I have taken on Coursera, this class had fewer features, less content, and seemed much less thought out.

This was a nice introduction to R for someone who has had previous programming experience. However, many of the lessons had simple grammatical errors in them, which is just unprofessional. Many of the swirl lessons were just the online material repeated, so reading the lessons then doing the swirl lesson was massive repetition. Also, many of the swirl "lessons" were merely "Type this in and see what happens!" which doesn't really teach anything. Finally, the final quiz material had spaces in the column headings which was fixable but added a level of monotony and inconvenience that was not needed.

While I do feel like I learned the material, the lack of video demonstrations and over-reliance on the textbook made this a much less pleasant class than most Coursera courses. In addition, the demonstrations of ideas were generally weak - in particular, the final quiz, where we were expected to combine datasets, was something that I didn't feel prepared for. It felt like I had to teach myself how to do this through my own research, rather than something that the class had prepared me for.
