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.

What I liked most about this course was that it gave us a solid foundation on how to program in R and at the same time made us want to learn more about it.

This course helped me learn functions I had not been previously aware of and really helped challenge me. I learned a lot!

A thorough introduction to the basic syntax of R, with a strong focus on understanding how to apply the key packages in tidyverse. I now feel like I have enough knowledge to conduct moderate to advanced complexity analysis on large data sets.

A well-balanced and professional course that really helped me understand and manipulate R datasets.

This course has a perfect combination of theory and hands-on exercises. I've been doing a few courses in Data Science on Coursera and I have found this method the best at least for me personally. I will probably carry on doing these courses. On the negative side, the student forum is practically dead, don't count on getting any help there. Coursera support have been very difficult and I had to wait a while to get my certificate. In the meantime Coursera charged me for an extra month (after I'd completed the course).

The course book is good and a nice resource. Swirl lessons were also really nice. They are interactive and helped becoming familiar with the functions. However, video tutorials on real datasets like the one from week 4 would be helpful. Also, the final quiz was disproportionally difficult in comparison to what was taught during the weeks leading up to week 4. Overall a good course that provides a solid introduction to R.

First three weeks materials are amazing, and I like to interactive with swirl(). If there are some more videos rather than reading materials, it would be interesting.

Good lessons but wish there was more lectures by the professors.

It is a very good course for new learners. However, it could be better if there is a R script writing the right code for the final quiz.

Excellent class. I had already done a lot of the swirls and would have liked that to be in my record somewhere, although it really wasn't hard--and was probably good--to repeat them.

You are very much on your own as far as figuring out methods and steps. Expect to use the forums a lot. The professor does a great job explaining but there's a gap between the lecture and the assignment. I compare it to not knowing what a circle is and then being asked to draw one just based on someone's explanation. You'd get better results if you were at least shown a curved line.

Can be vastly improved by making it more student friendly and giving more tougher practice exercises to tackle to assignments

There are a few areas of the course that are not fully explained and cause extra time trying to 'figure it out'. I am not referring to code/learning, but the logistics of the class. However, there are a few questions in assignments & quizzes that refer to things that were not particularly explained either in the lecture or in the book. I understand self study is beneficial, but I start the course with the understanding that questions will be based off of lecture or the book. If additional resources are needed, then that should be expressly stated in the lecture or book.

Good content, a lot of work loaded in the quiz of the last week, beware of this.

This course was just ok. Much of the information is a screen scrape from a book and peer-evaluation, so you may be better off just getting the book and going through it. The mentors occasionally participated, the authors rarely so,.

Excelent course to start with the basics of R language. It gives a modern introduction to R programming avoiding traditional topics like loops and conditionals keeping them for more advanced programming topics. It also covers almost all tidyverse packages with a shallow introduction to the most common packages.
I have acomplaint. The dataset for the final quiz was outdated, I managed to pass the quiz guessing variable names.

All in all good stuff. A couple of comments:
Swirl grading should be a little more flexible; sure cut is more succinct that nested ifelse's, but there's more than one way to skin the data-analytic cat in R, as I'm sure y'all are aware.
Also, I recommend more emphasis on data tables. I use them exclusively due to the dramatic performance improvement over data frames. And in my brief experiments, dplyr and tidyr commands worked on them too.
This first course was review for me. Nonetheless I definitely learned a few practical things that will up my data science game (which can always use upping).

Good course, but there were some technical hang-ups with the "swirl" package which made it difficult to submit assignments and get credit for completing them, even once you've solved the coding questions. This was very frustrating.
