課程概述

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....

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!

"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!

Course content was good, but assignments were too hard and not well linked to the rest of the content. I spent hours online trying to work out the assessments which then leads to the question of why the course

I learned a lot of the R basics, but I was completely lost for the week 2 + 4 'write a function' assignments - they strike at a level too high for a complete beginner for me (and that's after religiously taking notes and completing all swirl exercises.)

The assignments are too hard. Wish there were more similar example walk-throughs provided.

I would be cautious to recommend this course to a complete beginner. I had been using R for about 6 months before starting this course and found the content challenging. For instance, topics like lexical scoping covered in this course are usually tackled in a more Advanced R course. For a complete beginner into R, I would recommend a book like "R in Action" by Robert Kabacoff or the course on Udemy by Jose Portilla.

However, if you have had some exposure to R and would like it to take it to the next level, this is an excellent course. It will force you to learn things on your own. Read the documentation of R functions, peruse through stack overflow and really step up your game.

The gap between assignments and course content/exercise is too big. Assignments are very difficult to complete without programming knowledge.

This seemed unnecessarily difficult because I feel there was a huge gap between learning the concepts and the homework. I understand the "developing the hacker mentality" is needed but some things should not take so long. Maybe I'm just an idiot, but learning curve is huge. My recommendation is to be patient and google is your friend,.

I have a rudimentary background in R programming and a lot of experience with computers. I really doubt that someone with no programming experience would be able to complete this course. In many instances, the tools and functions needed to compete programming assignments were not taught. In addition, functions that are taught in the class are not used at all in the homework. The final assignment was unncessarily complicated and time consuming. I would not recommend this class to someone who is new to programming.

Great course, however I think it is particularly hard for those who never had programmed in R before. Moreover I think the Programming Assignments were quite hard regarding the topics being discussed during the weeks.

I have programmed in SAS before (15 years ago), so I thought that experience would be sufficient for me to take this class. I have to say it is not. This class is definitely not for beginners - you must have programming experience, R experience and/or both. The programming exercises do not follow the lectures and it does not build upon concepts. You will be required to seek help elsewhere (i.e., Stack Overflow) and answers to your questions will take days, if not longer. So, the fact that the classes are organized by week means that you will not conclude in the time you believe you will. I feel that this class is more self-taught than anything else. I have decided to quit this class as it has become extremely frustrating.

The course can be little more better for folks who are non programmers to begin with. This is an advanced course for a beginner/non programmer, hence would recommend to have a beginner course for non programmers/ R and then this course should be offered.

First off, I would like to thank you Dr. Peng for making this course. I am really happy to be one of his students and got the chance to learn so much about R programming. However, I am giving this course a 3 out 5 after completing it. The reason is that the assignments and final is extremely difficult and they do not connect so much to lecture videos. This course is 100 percent rewarding if someone can put all of their time and energy into it. But the difficulty is that if you are a starting out your programming journey, then this course can be "VERY DIFFICULT." The workload must be taken serious at all time!!

Very steep learning curve, especially in the beginning. the professor does not have a very engaging way of presenting his material. Also unfortunately he always requires to first think theoretical and then apply some of the learned content this for yourself. However teaching works the other way around:

1) what is the problem we are facing?

2) how can we solve that problem (practically)?

3) how and why does this solution work (theoretically)?

this is proven to be much easier to learn new things and get started. Instead i think this course is set-up for people to struggle by themselves, which i find very frustrating and its not teaching! I ended up teaching myself through trial and error and lots of google search. So what am i paying you for then?

Disappointing

This course lacked organizational structure. The lessons were not in a logical progression and the material jumped around a lot. Furthermore, once a topic was introduced in a video lesson, the practice did not correspond to the lesson just learned. This made it hard to reinforce what was just learned.

I would not recommend this course to someone with no experience with R.

I learned a lot, but 1 star because most of the HMW are extremely hard compared to the lessons, and has nothing to do with the lesson, they need more smaller and easier HMWs . The class need to be structured better.

It was always too hard to understand this course because of gaps between theory and practice. It will be much easier if you have a lot of exercises step by step mooving us to the final assignment. Like swirl but more sequential.

Questions asked in the assignments were on a much higher level than what was taught in the lectures. I get it that I should do my homework and refer other sources, but that defeats the purpose of watching the videos on Coursera itself.

Lectures could be more interactive, instead of simply having a running commentary on a ppt slides.

A little more explanation on how to program using R constructs would certainly help. The course suddenly throws us deep into the ocean with hardly any experience in swimming.

This is an excellent course but be warned, the programming assignments are difficult. If you do not have any coding experience, the assignments may be a bit challenging for you. But with the help of the internet and Github, you can complete them with no problems. The course content is great. All the videos and information are for beginners and are very helpful. The best part of the course was the swirl exercises it had you complete in R. Swirl exercises acquitted you with the programming needed for success in R. Overall it is a great course. Just understand that the programming assignments can be challenging for new timers.

Brilliant content!! Practice exercises really help you evaluate yourself. A little knowledge of R programming before this course is helpful as that might help understand the slides better. Though it is not mandatory but one can still utilize free resources available online to build the basic knowledge. Also, if you have prior experience with any programming language, that'll be very helpful. Would highly recommend this course.

The material poorly prepares you for the assignment and expects a deep commitment to a single part just to solve it. I was unable to find help in the forums or online despite doing well on the quizzes and other work. Terrible course.
