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!

Too short, too simple, too theoretic.

I found of little interest the slides, partially interesting the swirl exercise, interesting the programming assignment.

I would like to have a longer course with more practical examples.

the course is absolutely not for beginner who has little knowledge of R even they are interested in data science specialization... this should be made clear to avoid waste of time, efforts and budget.. not worth subscription

Very disjointed and no clear progression. While it teaches the basic syntactic rules well enough, the functionality of R is explored in an ad hoc manner where the assignments have little to no relation to the week's lecture.

The assignments are way too difficult in comparison to what has been taught, the instructor already assumes we are from a CS background.

1 extra star just for swirl exercises, they were highly interactive and informative

it was a really difficult and un-informative experience, I didn't get any useful info through the lectures or reading notes. and the assignment were super hard to get through. my worst choice for a data science course.

It is just not a good course for a beginner, especially the assignment 2 is hard to understand. And hope this course can add a little bit material on statistical programming or machine learning session in the future.

There is not much of a relation between what the course gives (explains with the videos and with the SWIRL exercises) and the real exercices they ask to. Too difficult to follow by people new in the programming area.

The assignments were extremely difficult and there was not much of help directly from the videos or lecture material to learn and do smaller programming assignments that could be used when doing bigger assignments.

A huge lag between what is being taught, the swirl lessons, and the programming assignments. I'd definitely not recommend this course, unless and until you're already well versed with most of the functions in R.

The lessons were easy to understand. However, there is a huge gap between assignments and lesson videos. I personally believe it is not possible to do the assignments with the help of lectures and notes alone.

Swirl is good. lecture are awful. Does not teach the necessary knowledge to be able to pass the assignments. The assignments feels real and the knowledge you need to learn somewhere else to pass is useful.

I don't think the course is setup for a beginner or a person who has never used R...very frustrated with needing to search the internet for help on everything that the course is supposed to be teaching me.

Impossible leap of difficulty between assignments (especially Week 2) and lecture material. Poorly designed and in serious lack of guidance. However, the quizzes help consolidate knowledge from lectures.

The textbook is great for notes, but I would have loved to see more applicable examples of how to use the code. The instructor pretty much reads the textbook to you. Don't feel like I truly learned R.

Not a great course as said by the community. Most of the assignments are not even related to what is taught by the teacher and the way the teacher teaches makes learning R quite boring and cumbersome.

every time i watched the videos i ended up falling asleep. not at all engaging and professor makes it difficult to learn and build upon basic concepts. my only saving grace was prior exposure to r.

This is not R for beginners.. I am sure many people trying to get into R have been discouraged. There is so much great things you can do in R without making it that complicated as it was done here.

The swirl exercises were helpful, but the video lectures and assignments were not. Therefore, I cannot recommed this course. There are better resources for learning R in general and R programming.

The assignments are highly dissociated from the course material. Also once the due date has passed sharing the best solution would help so as to give insights on what could have been done better.

Lessons and assignments were not aligned, expected beginners to know advanced R topics in order to complete assignments. Good info and would be better if lessons and assignments aligned better.

It was very difficult to solve the projects . I think I should have more coding experience or analytical experience before attempting this course. The practical exercises should be more to do.

This course is not much good because of some topics are not clearly explained Like Loop Function and 4TH week also. Assignment was so much tough and not related to the topics that covered ..

Massive gap between learning materials and assignments. Even with taking notes and going through additional swirl exercises you don't feel prepared for the assignments. Note: beginner in R.

In the lecture, they didn't mentioned enough function to use in assignment. I just stared to my computer couple hour and didn't know what I should do. T^T Take many time to figure it out

Good luck! Without prior R background, you will struggle. The professors will be of little help. Post your problems to other internet forums, you're more likely to get help and faster.
