Really interesting course. The interactive coding sessions with swirl are especially useful. Would be great, if you provided sample solutions for the programming assignments, in particular for week 4.
"R Programming" forces you to dive in deep.\n\nThese skills serve as a strong basis for the rest of the data science specialization.\n\nMaterial is in depth, but presented clearly. Highly recommended!

I did not enjoy this course at all. Even though I work as a software developer, this "Introduction to R" was very boring, and the lack of real examples in the lessons made me very confused as to why we do stuff.
More over, the assignment level comparing to the content in the videos is too high in my opinion.
The only thing I enjoyed through the course was the swirl package.

If you read the 4 and 5 star reviews they are people who have R experience already. The only prereq for this course is supposed to be regression experience only. This is definitely a learn completely on your own with the videos and text provided by the actual course completely useless. If you are new to R or any programming at all this course will do very little for you.

In desperate need of an ISD. Very bad descriptions, the quizzes are not sufficiently built around the lecture content, heavily relies on using an "optional" external module which is vastly superior to the actual course content....but the external module is only presented at the very end. Not impressed. Far too much external searching for unaddressed concepts and ideas.

This is one of the worst course i have ever taken on coursera, the assignment is so different from what was taught in class, in fact they have nothing in common and the instructor gulps so much and so frequently and he teaches as if he is in a hurry, if there was a lower rating than 1 star, thats what i would have rated it, i spent months on this course. awful

They say that this course is for beginners, but it's really not! Someone recommended I take this course to get ahead in my career, but honestly it takes hours on end to learn and the slides are unclear as well as lack basic information to learn. I had to use the internet a lot as well as a friend to teach me basic concepts otherwise I would have been lost.
Death by power point. If you can learn from essentially listening to a pod cast and reading unix type manual pages, then this course is for you! If you're like the rest of the population, then these lecture videos are useless. The only redeeming quality to this course has been the homework, but you can find them online or come up with them on your own.

There is an incredibly wide difference between the levels lectures and the exercises presented on Swirl and the coding needed to pass the assignments. This is a huge detriment to the learning objectives of the course.
It seems like the "lectures are about addition of two numbers" and the "programming assignments are like differential calculus".
por Arne K•
To my opinion there's a huge disconnect between the lectures and the programming assignments. A lot of functions/programming required in assignments is not taught in the lectures and thus need to be looked for in other sources. Moreover, the lectures contain a lot of weak languange making it unnecessarily difficult to follow.
por James S•
Completely lost. This is not meant for rank beginners. Data Camp's free R course has been much more helpful for me than this. It doesn't have the same level of detail as this, but at least I'm not watching an instructor gloss over concepts or ideas that are completely foreign to me as someone completely new to programming.

Had the toughest time doing this course. A huge lag between course content and the assignments. Kindly consider upgrading the course content so its better designed for beginners. Or at least consider providing additional reading material or helpful information. This course is hardly becoming of a John Hopkins' course.

1) The faculty should talk more about the slides, draw on them. It is hard to follow in the current form. 2) The assignments are not relevant to the learning, except week 4. 3) The faculty speaks too slow. I listened to him at 1.5x speed. 4) Plotting should have a bigger part in the course. 5) SWIRL is GREAT!

The course lacked overall structure which really impedes learning. There was barely an explanation of why we were learning a particular topic. I believe it might be really helpful to have an overarching project that we work throughout the course, and new topics are introduced in relation to that project.
Only the most basic of instructions for R, which are bland and easily read in the documentation or other free resources. There are very few best practices or real examples to use anything found within. The quizzes and assignments do not match the lecture material and are contrived. Not worth the money!
por Eric J S•
The lectures never motivated the subject matter. The material should have been broken up across multiple courses and be introduced as needed. The course difficulty was highly uneven, expectations from the lectures were noticeably lower than expectations for the quizzes and especially the projects.

Don't do this.Don't waste your time.The instructor teaches you like normal A,B,C,D and the assignments were like go to the moon and come back within half-an-hour.
Watch how Dr. Chuck designed his PYTHON FOR EVERYBODY course and the assignments and learn how to design course module .Disgusting !!!
por Thomas A•
Course has the appearance of being quickly thrown together. Assignments are impossible to complete due to random number generation mismatches. Lecture content frequently does not really help with the assignments, and a lot of the video information is extremely useless in real world applications.
por Rodolfo N R•
Professor is not good, his English is awful and does not explain in a easy way what he tries to teach.
Content is not organized and tasks are not aligned with the content.
I have to say that I won't recomend this course, however, I would like to help to improve this course if you need help.
por Luis G M D L C•
Very painful training, the contents reviewed in the material will not make you capable to solve the weekly assignments, you will have to learn what you need on your own. To me the only value added of this course is that I will receive a proof that I know how to define basic functions in R.
por Arjun N•
The course is misleading - the difficulty ramps up too quickly, with the result that those who do not have a programming background will not be able to keep up. It should be toned down and reworked, or split into two courses. Cramming everything into 4 weeks makes everything too difficult.
por Maneesh K•
The teacher goes very fast with the concepts without really spending much time on each of them. It will be great if instead of covering all things in short amount of time, the teacher could write R code using each type of function in console so that students know exactly what to expect.
por Albert W•
The gap between the lecture materials and programming assignment is enormous. So much of lecture seem to be on the history and theoretical of R programming that it completely fails to cover the material needed to actually completed the programming assignments. Incredibly disappointing!
por Afia M•
Only take this course if you're already familiar with the basics of R programming, otherwise don't bother. The instructor is no help and you'll have to search the internet to complete the required assignments. Don't know about skills but this course sure gave me a lot of stress.
por Lefteris L•
The lecture material was very poor in terms of content and barely scratched the surface of the topic. I don't consider that passing this course you will learn anything but the very basics of R programming. In that respect you are better off reading a book on R.
por Jasen N•
For an introductory course with no prerequisites, the assignments should cover material that has been introduced in lectures. Non-introductory and advanced courses in R can require students to look outside of lectures for completing relatively complex problems.
por Sydney R•
BEWARE. If you are someone who is new to more advanced math or to any sort of coding, this course will be very confusing, totally unpractical, and you'll walk away not feeling like you've really learned how to use R in a real way.
I was incredibly disappointed.
