"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!

Excellent course! I already knew a lot about R - but this class helped me solidify what I already knew, taught me lots of new tricks, and now I have a certificate that says I know `something' about R!

The course content and swirl online assignments are at the beginner level, but I feel the assignments are above the beginner's level. The assignments do not align to the course content and the forum has little value added due to the congestion with people asking for assignment reviews. Recommend stating in the course content the appropriate section in the book (for those who buy the book).

The workload and the structure of the course was vastly different from the previous session. I had a very hard time to follow and to keep up with the pace at times and had to play catch up often. I wish there were more exercises to help the students familiarize with core functions and concepts instead of throwing them into the deep end and wait for them to "grind it out."

Las evaluaciones no tienen el mismo nivel que las clases. Se ven temas en los videos para que a la hora de hacer el examen se introduzca (breve y muy pobremente) otras funciones y estructuras que nunca se mencionaron antes. Durante los videos se muestras funciones que se ven hasta semanas mas tarde. No recomiendo el curso. Aprendi mas por medio de los modulos de swirl.

I'm finishing the course happy due to the certificate, but I am also very frustrated. The assignments are very unfair when compared to lecture contents. If you don't have any previously knowledge in R, it is very difficult to conclude the course. In addition, the auxiliar materials are in the week forum, and not as obligatory readings. I am very upset and frustrated.

I do not recommend this course to a complete beginner. There is a huge gulf between the coursework and assignment, I spent countless hours in solving the assignments and eventually had to take help from the internet. The theory part of the course is also taught very dry, where the professor is just reading lines in the slides. I regret subscribing for this course.

While the information provided in the lectures was helpful and instructive, the programming assignments demanded far more information and skill than was provided by the class. This could be rectified by adapting the lectures to reflect the skills necessary for the programming assignments, or adapting the programming assignments to the skills presented in lecture.

This course was difficult for me to grasp. The instructor (I believe) assumes that all participants have some background in programming, and since I do not, I have a very difficult time following the examples. I bought the entire series of classes, but need to retake this one after I read some more from other sources and have had a chance to digest what's here.

The Course is not easy for someone who is new to programming languages, I myself with 2 years of programming knowledge with other languages I found it difficult to understand, the only thing I liked about this course was swirl training it was pretty easy, fun, and clear.

Assignment was too hard and the descriptions are not that clear specially assignment 3

You don't really learn what you need from lectures. While I agree part of the experience is having to search and figure things out yourself, this goes beyond what I would expect. I have a technical background (heavy database, Data Warehouse, sql, and coding) and it was difficult for me, I can just imagine if you didn't have a technical background.

While one will learn the basics of R from this course, the teaching/lecture material can be improved significantly. One has to do significant research/self-study to do the exercises. The content from the mentors help a lot. Those contents should be incorporated into the lecture material. I like to see this course improve based on the feedback.

The material and concepts covered in the lectures are basic and simple, without clear exercises and practice examples. When it is time to solve the assignements, they overwhelmed you, are far advanced and confusing compared to the topics of the lecture. This is not an introductory course for people without knowledge in programming.

First of all you will get a basic idea about R programming. Highly suggesting to use the swirl packages to get a overview of what the theory is saying. but the assignment difficulty level is too much for a beginner in programming. i would suggest those who have a lot of time spending for this course to enroll in it.THANK YOU

good explanation regarding the topics, but they are just rushing into it and they are missing few basics things to tell, and one more thing is "everything is in PPT and there is no explanation or practical by doing coding in Consol" we cant understand until and unless we do in practical right! Rest everthing is fine Thank you.

The instructor seems not to be well prepaired. Sometimes he can´t even speak one sentence without "Ähm", "tz" or something like that. The quality is very bad!

Sometimes the contant is too less for the program assigments.

It is a good introduction for "R programming" but you definitly need more to get really into it.

The video lectures were not on par with the, in my opinion, extremely demanding programming assignments. I'd say some knowledge of advanced coding was required in order to complete the assignments, or alternatively, lots of time to learn by yourself on google and forums, which wasn't really the point, was it.

Very essential topics, but the instructor's delivery of content is inconsistent, glosses over explanations at time, "umms and arrrs" a lot, talks extremely fast at times. Making this course quite hard to follow.

Disclosure: English if my first language. Not new to programming. Not new to MOOC courses.

I was really hoping to complete the data science specialization, but I have found the first couple of courses to be not very cohesive. This course in particular was ok, but lectures and application (projects and assignments) had such a wide gap between them I found that I was mostly teaching myself...

The video tutorials are good. But the assignments given are way above the top. The course structure should incorporate those topics also which is expected from the students in the assignments. Restructuring of the course is required. Overall, the course is good for a starting point in R Programming

The assignments are soooooo difficult for beginners. I spent most of my time trying to find solutions for some functions that I am not sure if they can be used. Many solutions used in assignments are not covered in materials and videos. One thing that is interesting and helpful to me is the swirl.

Not built for beginning programmers. Lectures and programming assignments are nowhere close to the same level. A lot like teaching someone the alphabet and then asking them to write a short story in the same lesson. First things, first. I'll probably explore on my own or with free courses/videos.

As far as learning R Programming goes, this course is ok. When I first took this class I was having a hard time grappling with R. As a programmer who knows C++, VB, Java and Python, I felt it should have been easier to grasp. It wasn't until I started doing research outside of this course that

As someone with little programming experience, this course was extremely challenging and I don't think the information taught was enough to successfully complete the course. I had to go to another online education source to teach myself R before I could do the Coursera programming assignments.

Swirl package contents were better than the lectures in the videos. The video lectures introduced concepts without any context, making them difficult to understand. The video lectures also didn't demonstrate anything. The Swirl package was much better at "showing one," "doing one."

This course requires those who already know how to program in R before taking the course. Although the lessons and quizzes are doable, the assignments are way too hard and is not even covered by the lectures. I had to abandon this course because I could not do the assignments.

The lectures and the book only gave a general overview of what is needed in order to answer the Assignment and the quizzes. This course is only good for getting a general idea of R Programming, but the material is barely sufficient to prepare the learners for actual problems.
