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.

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.

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.

Could have been better. Expected some interaction/videos from the mentors.

Very informative, however could be more complete. Some functions aren't introduced and the swirl package didn't accept other solutions path that would likewise lead to the same result. I believe also that some update would not harm. However, this course is really informative and, in my opinion, one of the best available. I really enjoy this course. Nice job and thank you very for sharing this knowledge.

the last exam is very hard, which need more knowledge than what you learned in previous chapter. the forum is not very helpful. lots questions are either not answered or answered with delay. But overall, you can get the basic concept from the course.

Une initiation intéressante et complète à R qui a l'avantage de donner des bons réflexes pour coder rapidement. Le caractère interactif des exercices de programmation est un gros plus. Attention : il n'y a pas de vidéos hormis la vidéo d'introduction. On peut aussi avoir des difficultés de syntaxe susceptibles de nous bloquer un bout de temps, notamment sur des fonctions où la documentation est un peu aride (je pense à cut et à spread sur lesquelles j'ai bien passé 1/4 du temps que j'ai consacré au total à ce MOOC).

I liked the swirl() package a lot, made me jump into writing codes into RStudio straight away. My only wish was to have some videos that would push me further

Course is good. However, some of the packages discussed in the examples, such as ggplot etc. should be discussed in more detail.

The material gets progressively tougher but I never felt totally overwhelmed. My only feedback is for the mentors to be more responsive in the forums - if we're posting it means we've already thrown everything at the question and still couldn't figure it out.

This is a good introduction to R but I do wonder if there could be a little more content, particularly in week 4.

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.

A very nice introduction to the R programming environment. I learned a lot and it was fun to do!

It's a great course for those who are just starting to learn R, It provides enriching for data analysis, however as a constructive feedback, I feel there could be improvements around how the exercise are planned and the submission process for the exercises

Very good starting course, covers all the basics.
My 2 cents: I would prefer more tests like the last one than the swirl lessons, they're more challenging thus you learn more.

Excellent intro to using Tidyverse (dplyr, tidyr, readr) to manipulate and clean data in R. Occasionally the readings and the SWIRL homework don't quite match up, but it's not a dealbreaker by any means. It was definitely worth my time overall.

I like the swirl exercises, but found the text lessons to be very short. Overall, good but I hope some video will be given in future modules.

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

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,.
