Sobre o curso

In this course you will learn how to program in R and how to use R for effective data analysis. You will learn how to install and configure software necessary for a statistical programming environment and describe generic programming language concepts as they are implemented in a high-level statistical language. The course covers practical issues in statistical computing which includes programming in R, reading data into R, accessing R packages, writing R functions, debugging, profiling R code, and organizing and commenting R code. Topics in statistical data analysis will provide working examples....

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.

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!

Wow. I cannot believe how difficult that last week was. No explanation for how to go about it just a learn it in your own time. As soon as the $49 USD is taken out of my account the difficulty is raised considerably. Cannot believe I paid for this subject.

This course is poorly structured and the lessons don't prepare you in any way to complete the assignments. Don't waste your money taking this course and find something else. Johns Hopkins University should be embarrassed to have their name on this course.

The lectures are good for basic understanding, but there are no sample programs in order to understand their real world application. And the assignments are not at all for beginners. There is a huge gap between the content and the assignments.

To be honest, this is the most terrible course that I have ever had on Coursera. The courses are not well organized, and the assignment has little to do with the videos, which means students have to learn by themselves to finish the assignment

Poorly organized and managed. Each week of this course should have been broken down into individual 4 week courses. I have 20 years software development experience, and I can tell you this is too much information to cram into a single class.

The new platform Sucks!!!

The people who just want to learn for free and not purchase a certificate are barred from attempting the quizzes unlike the old platform. Not being able to take the quizzes completely ruins the learning experience.

You don't have to go through the videos which I found painful because of the instructor's voice. The textbook includes everything in the videos. However, there was no application for the videos and textbook in the quizzes and assignments.

I really wanted to learn R in my current Mac iOS environment, in a Linux/Unix environment. I only see here the course offered in Windows environment in archaic MS-DOS environment? I am not interested in that. Hence I unenrolled.

Somewhere during the second week there is a gap in coding that I could not overcome and this ruined the whole interest in pursuing the course because in order to overcome it I had to cheat. I don't feel like I am learning anymore.

This class is a travesty in learning R. The lessons are misguided and do not prepare you for the overwhelmingly difficult homework assignments needed to complete the course. I would not recommend this to anyone trying to learn R.

The topic which was discussed by the professor can't match with the assignments and quiz.

I think the video of teaching should add more elements of practice, so that it would fit people with no basic knowledge of programming more.

There is a significant gap between the lectures and assignments. For someone with very limited programming background, this posed a great hindrance to my ability to use the resources provided to be successful on the assignments.

Possibly the least well structured class ever. Also, not made for people to actually learn how to program in R. It is sad that I paid for this, and ended up going to another resource to learn... and it was much much easier.

Not a class for the beginning programmer. The lectures do not line up with the assignments, and if you don't have programming experience, you could easily spend 10-20 hours/week figuring out how to finish the assignments.

The ask in the fist assignment was not formulated correctly. Felt the class needed more hands on learning. Although the lectures were clear and concise, going back to them really didn't help me with the assignments.

I think there is a total mis-match between the lesson material and the assignments. The amount of hours one needs to search the internet to augment the training. The recommended text doesn't even come close in

I don't feel like I really learned R from this course. I felt like they just made me aware of some features. Also, there was vast difference between the course lectures, swirl and actual assignments.

The assignments had nothing to do with the lectures. The teachers do a poor job of explaining basic concepts and theories. The class is a lot more advanced than the class description makes it seem.

The assignments are too hard for the lessons that we had it made me frustrating, after week 2 I completely lost and didn't know what should I do .

I really don't recommend this course for beginners

This course is the worst course that I have taken so far. I am not happy with the course content and the way that the lecturer uses to teach this course. I really want to refund my money!

There is a wide gap between the lectures and the practice. Its clear that the video material is completely inadequate and insufficient for the course. A poor introduction to programming.

por Jonathan H

The jump from the lecture material to the assignments was way too much. In order to complete the assignments, one needs to spend lots of time learning things not covered in the course.

The course content does not match the material you are tested on in the assignments and quizzes. DO NOT take this course if you are looking for an introductory level coding course.

Assignments don't match the lectures at all. Lectures are dry and simple and don't help you understand how to apply the topic to a real life situation. Don't waste your money.

Week 2 is an unreasonably difficult jump from Week 1. This course's beginner friendly lectures do not align with the level of understanding needed to complete the assignments.
