The only problem was the gap between assignments' difficulty and lecture videos. But assignments were really good.

Overall it's good. And I think PPT may be much more helpful if there is a video of professor, and some animations.

I have learn lot things about r programming.its most useful to take next step and thankful to all teaching staff.

Thanks for the professors' dedication to this quality course. Hope that the course videos could be more engaging.

Great course overall. Basic principles for using R are covered. It could cover a bit more advanced tasks though.

Course is good start in R programming. Questions in the quiz may be dynamic. i.e. should not be same every time.

Swirl package really gave a lot. The lectures I find to be at times a bit slow-paced. All in all a great course.

Learned a lot from this course but for people without any programming background it might be quite intimidating.

More work has to be put upon working with examples that would help solve quizzes and not only depend only swirl

Lectures and assignments are quite misaligned, should incorporate a more progressive assignment routine instead

More interaction is needed and explanation for programming assignments other than that every thing is excellent

week 3 and week 4 assignments were so hard to solve ,

hope you improve the way of writing the problem statement.

I am experienced in C++/C etc and some 50% of the videos i had to rewind.

The assignments are really good though

The course lessons are very easy and helpful but the assignments are much harder compared to the week lessons.

for the last programming assignment, i didnt find the instructions, had to search on internet what i had to do

Dr. Peng is awesome! Thank you very much. I hope there are pre-requisite videos for beginners in R! Thank you!

Really great course. 4 stars for not allowing submissions of quizzes and program assignments without purchase.

Great course for learning the basics in a structured , concise way.A bit basic but a great course nonetheless.

There was some mismatches between what was thought in the lectures and what was tested as part of assignment.

I learned a lot about R programming and code scripting. Assignments were a little harder of what I expected.

quite an intense course, ok to follow the assignments and lectures, but the last assignment is a killer. haha

I wish to learn the language and master it. The course provides very good understanding of the basic concepts

Videos were really good ,but then the assignments were complex and not related to what was taught in Videos.

If the lecture could be practical (i.e... lectures + working it on R console), I would learn it even better.

a very descriptive course on r programming. a good guideline for who want to make a future in data science.
