Good course, but very specialized programming knowledge in this particular course, which was not the case with other courses in the specialization. Would only recommend this course for those with the necessity to build R packages.

I learned a lot in this course, was difficult at the begininng but enjoyable at the end!

Informative and gives lots of information

You will learn how to develop, publish and maintain a R package, and it's quite an interesting skill that will change the way you manage your code (you'll probably always store your code in documented packages you'll host on gitHub then).

Though it's a pertty hard MOOC for many reasons : quite inactive community, information you'll get in lessons isn't enough to complete assignments, course material is just book you'll have to read (no video, no interaction), you'll probably have the feeling you're going through something that's not really finished. Don't follow this MOOC if you want to avoid being frustrated because most of the time you'll be.

Course material is a bit light, missing useful pieces of information. The example code is functional but not of sufficient standard to pass the documentation exercise. The solutions to the exercise are not covered in the course material. It takes a lot of outside work to get a good mark. Course is good, but the material needs a bit of work.

This course was not great. Almost all 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 very occasionally participated, the authors never. The assignments are poorly written and missing too much detail.

Easy at first, very challenging at the end. Some of the course materials really need to be updated and expanded. Mentoring should be improved (include mentors on this course).

The content was good but I have missed the videos. I can read a book, the experience with video demonstrations is better than this aproach.

The amount of uncovered yet crucial issues is too damn high. For week 4 assignment I did most of my research on stackoverflow.

It was a very challenging course at least for me but i think it is not necessary.

Basic course no more then that

The material is not bad, however, this is just a refurbished version of a corresponding book written by the authors. Literally, all the readings are just excerpts from this book with typos all over the place. Save some money and just read that, I think this is a minimal extra work cash grab and you feel that all throughout. The final project is fine but not too fun (and the reading material is insufficient for it), it isn't worth the money either.

Lots of outdated material and no mentors remain to assist. Documentation is incomplete and left to the user's imagination. There have got to be better courses than this.

The materials is not logical and not enough. It makes a lot of difficulties for the learners, especially through self-learning and online learning.

Whish we would have a video going through all the steps (real case example) to show how to build, test and use travis on a package.

Among the worst courses I have found on Coursera. Once again, just a bunch of text, cut and pasted (sloppily) from their book and other resources. Examples are poor and insufficient, and much of what they ask you to do in the project is not covered well, or at all in the course forcing you to learn on your own. I don't object to self-education, but then, why bother taking this course? Can't believe they are charging money for this.

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.

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

Great gap between teaching and what is required to pass the course. Unnecessarily difficult. Not recommended.

Just reading. There are not videos.

You are not allowed to submit the quiz if you do not pay.

Iam actually waiting for over one week to get graded. I dont want to pay for waiting!
