About the Course

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!

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.

The speaker has his microphone far too close to his mouth so you can hear any(!!!) noises he makes (and he does it a lot!). Further he uses a lot of non necessary commands he does not or just sparsely explain. this would be okay if he wouldnt slip every second sentence or repeat one word several times. He also does not execute code, so you can't see, what the code actually would do. some youtube videos guided me much better than this through basic R. Sad.

This is way too esoteric. The content was delivered way too fast for me to keep up and process it. This needs to be taught with more frequent hands on examples. I'm also not sure why, if auditing, we can't submit and see how we're doing on the learning. I have no way to evaluate if I'm picking up the concepts or not, which is a struggle. Overall, I would not recommend this course for R beginners. I would look elsewhere.

There's a major disconnect from the basic teaching material provided and the first big quiz. All of the actions that need to be taken to complete the quiz is not provided in the lesson material. I understand the interest in teaching people how to look elsewhere for help and learn how to ask questions on forums, however as students in this program will be in their infancy in this program, we do not know what to even ask.

This course is not beginner coding friendly . The assignments contain instructions and code that were not explained in lecture. The first coding assignment has students utilize concepts only found in stickied threads in the discussion board. The second coding assignment also decides to toss another coding function not explained in lecture. I give this a 1 star based on how unsupported I feel by the lecture material.

Teacher was super boring and it was difficult to grasp the concepts. I would not recommend this especially to beginners, the course makes it seem a lot more difficult than it actually is, you should try learning from other sources. On top of all that, if what is taught in this course is addition, the assignments are on Laplace Transforms. I had to do a course from somewhere else just to finish this one.

Instructor routinely introduces new functions while trying to explain another new function, and requires assignment submissions using functions either briefly encountered, or not yet covered. Course would be much improved by using only previously covered functions during explanations, and not blasting many rarely used advanced functions along with more common and practical beginning functions.

I'm giving this course one star because zero stars is not an option.

I wish I had read course reviews prior to beginning. First assignment was tough... but do-able. Second assignment seems straight forward, but the template they ask that you follow contains small tricks which appear to be FAR BEYOND anything touched on in lectures.

I'm actually going to fight for my money back, what a scam.

This course was frustrating, the learning curve nearly vertical, the material dense and inaccessible, and the evaluative assignments impossible for new users of R without outside resources. No one should take this course unless they are powering through it for the Data Science specialization. Otherwise, would-be students should just buy an R For Dummies book, and use materials elsewhere.

I found this to be the weakest course yet ( poorly guided, poor instructed, and huge assumption of prior R knowlegde. The main issue is that there is NO online chat capability. I spent over 7 hours trying to work out an issue in RStudio and Github all because of the really , really poor instructions. I'm not happy and so much so that I am not going to complete the rest of the modules).

I did not enjoy this course at all. Even though I work as a software developer, this "Introduction to R" was very boring, and the lack of real examples in the lessons made me very confused as to why we do stuff.

More over, the assignment level comparing to the content in the videos is too high in my opinion.

The only thing I enjoyed through the course was the swirl package.

If you read the 4 and 5 star reviews they are people who have R experience already. The only prereq for this course is supposed to be regression experience only. This is definitely a learn completely on your own with the videos and text provided by the actual course completely useless. If you are new to R or any programming at all this course will do very little for you.

In desperate need of an ISD. Very bad descriptions, the quizzes are not sufficiently built around the lecture content, heavily relies on using an "optional" external module which is vastly superior to the actual course content....but the external module is only presented at the very end. Not impressed. Far too much external searching for unaddressed concepts and ideas.

The worse Coursera course I've ever taken. The videos feel like someone reading the technical documentation to you, the "interactive" tutorials are like an 1980s text-only game, and the assignments require massive leaps in ability over what you learned in the lessons. I would call this course "Advanced-level assignments sure to both bore and frustrate people new to R"

This is one of the worst course i have ever taken on coursera, the assignment is so different from what was taught in class, in fact they have nothing in common and the instructor gulps so much and so frequently and he teaches as if he is in a hurry, if there was a lower rating than 1 star, thats what i would have rated it, i spent months on this course. awful

They say that this course is for beginners, but it's really not! Someone recommended I take this course to get ahead in my career, but honestly it takes hours on end to learn and the slides are unclear as well as lack basic information to learn. I had to use the internet a lot as well as a friend to teach me basic concepts otherwise I would have been lost.

Death by power point. If you can learn from essentially listening to a pod cast and reading unix type manual pages, then this course is for you! If you're like the rest of the population, then these lecture videos are useless. The only redeeming quality to this course has been the homework, but you can find them online or come up with them on your own.

There is an incredibly wide difference between the levels lectures and the exercises presented on Swirl and the coding needed to pass the assignments. This is a huge detriment to the learning objectives of the course.

It seems like the "lectures are about addition of two numbers" and the "programming assignments are like differential calculus".

Completely lost. This is not meant for rank beginners. Data Camp's free R course has been much more helpful for me than this. It doesn't have the same level of detail as this, but at least I'm not watching an instructor gloss over concepts or ideas that are completely foreign to me as someone completely new to programming.

Had the toughest time doing this course. A huge lag between course content and the assignments. Kindly consider upgrading the course content so its better designed for beginners. Or at least consider providing additional reading material or helpful information. This course is hardly becoming of a John Hopkins' course.

1) The faculty should talk more about the slides, draw on them. It is hard to follow in the current form. 2) The assignments are not relevant to the learning, except week 4. 3) The faculty speaks too slow. I listened to him at 1.5x speed. 4) Plotting should have a bigger part in the course. 5) SWIRL is GREAT!

The course lacked overall structure which really impedes learning. There was barely an explanation of why we were learning a particular topic. I believe it might be really helpful to have an overarching project that we work throughout the course, and new topics are introduced in relation to that project.

Only the most basic of instructions for R, which are bland and easily read in the documentation or other free resources. There are very few best practices or real examples to use anything found within. The quizzes and assignments do not match the lecture material and are contrived. Not worth the money!

By Eric J S

The lectures never motivated the subject matter. The material should have been broken up across multiple courses and be introduced as needed. The course difficulty was highly uneven, expectations from the lectures were noticeably lower than expectations for the quizzes and especially the projects.

Don't do this.Don't waste your time.The instructor teaches you like normal A,B,C,D and the assignments were like go to the moon and come back within half-an-hour.

Watch how Dr. Chuck designed his PYTHON FOR EVERYBODY course and the assignments and learn how to design course module .Disgusting !!!

Course has the appearance of being quickly thrown together. Assignments are impossible to complete due to random number generation mismatches. Lecture content frequently does not really help with the assignments, and a lot of the video information is extremely useless in real world applications.
