Very challenging, but good course. I've been programming in R for over a year, but there were still some things for me to pick up in this class. Assignments were a challenge, but satisfying to tackle.
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!

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.
By Gemelee H•
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.

I think that teaching a bunch of informations in few videos and after that asking the student to directly write a complex code is something that doesn't work. At least for me didn't work. Big thanks to swirl which was the only reason that I learned something from this course.

Not bad, but certainly not good. I cannot believe there is a style of teaching where you never get to see the best way to do something. I can slog thru the programming, but I doubt it's the best way to do something, but I never get to see how something should have been done.
By Sebastian S•
Good course. But definitly NOT FOR BEGINNERS. The videos and material are well-designed, but for the Assignments you need at least a bit experience in programming, as you need some functions and arguments the course didn't cover. The last Assignment is very time-consuming!
By Seyedabbas S•
The lectures are extremely boring! I am just watching them to make them green! I have to watch other lectures and read more by myself to understand the subject. I am sorry to say it that direct, but having a robot reading through the slides would not change anything!
By Ismail B•
The course is not tailored for beginners . The lectures do not prepare you whatsoever for the assignments. If you want to understand half of the material , you need to complement this course with other R learning material online. This course needs a drastic rework...
By Samantha M•
So far I am learning more from the Getting & Cleaning Data course, in a more structured and easier to absorb manner.
The Swirl courses were good; however, these are freely available outside of this course.
The lectures do not seem to align to the course content at all.
By Yu S T•
This course is for people to know about R if you have never used that, Don't take this course.
When I took this course I did not know anything about R, the videos in this course have never helped me. I had to take other basic courses and search the internet to pass.
By Mark B•
Not meant for a complete beginner. I've spoken to a dozen people who have taken this course, and if you don't have some programming skills, you'll struggle. I'm not suggesting its not doable for the complete beginner, but the time commitment may be prohibitive.
The exams and projects are really really hard and make R newbies, such as I, feel very suffering. And these contents are not connect to the teaching materials closely. I think there is large space to improve this course to make it more accessible and learnable.

The things that were taught in lectures were nowhere close to the programming assignments given. Either update the lecture to match the assignments or update the assignments to match the lectures to make the course friendlier and easier to learn for 1st timers.
By Katherine K•
informative but definitely for people who are far more advanced in background knowledge with R. The professor goes very quickly and the course jumps to new topics without much explanation or guidance. No good way to get help or ask questions if you get stuck.
By Han L•
The programming assignments are way above the information given in the lecture. Extremely difficult to do for people have no previous experience with programming. Swirl is probably the most helpful element in this entire course regarding learning R.
By Ravindra S N•
I didn't like it. Inspite of having done some courses on coursera(like Machine Learning from Stanford, SAS Programming from SAS) and edx (Python, R), many things went above my head. So I have decided not to pursue this Data Science Course further.
By Marie C N•
The course assignments were very hard for me as a beginner in using R and without a background in coding. The swirl exercises are good but they don't really help with the assignments. I had to rely on a data scientist friend to learn what to do.
By RODRIGO S P J•
The course content was good. However, assignments were complex and not very much linked to the rest of the content. Alhough it wasn't said in the beggining, I believe previous knouledge on programming or on R itself is needed for this course
By Beverly U•
The lectures did not prepare for quizzes/assignments. Not a class for beginners.
It would be better if he used R while lecturing instead of just talking through the whole lecture.
I got more out of the swirl tutorials than I did the lectures.
By Sara F O•
Firstly the videos and the swirl practice were very good and I leart a lot from them. However, the assignments were very difficult. There is a huge gab beetwen the content of the course and the assigments. This course is not for beginners.
By Andrew C•
Better than the Data Scientist's toolbox, but not a great introduction to R. When I'm learning a new language, I don't want to know about data types and for loops. A detailed example showing the strengths of this language would be better.
By Prasanjeit B•
The quiz were far advance than the material and somewhat disjoint from the topics.The overall lecture is good but not sufficient for learning R, Week 3 and some parts of week 1 could have been explained far more better than it was done
By Josh D•
Far too quickly moves from basics of R to advanced statistical programming. Needs better build up of skills. Swirl was useful, as the videos were essentially unhelpful. Many other better resources on introducing the content elsewhere.
By Jonathan T•
Assignment is way too hard without any guidance - course as mentioned in their earlier lectures are meant to go online and ask. Even so, there is no way for beginners like us to understand what our questions should pinpoint to.
