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.

"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!

If you enjoy floundering helplessly and feeling incredibly stupid, this is the course for you. Expect a few slides on basic concepts (all of which you need a VERY large screen to read because they seem to all be in 8 point font), and then get flung full force into coding. There are no worked examples. You might as well just buy a Reilly book. My partner and I both wanted to learn R for econometric analysis. He can do more after a 1 day seminar than I can do in a month struggling with this course. I had considered pursuing a graduate degree at Johns Hopkins, but if this is the level of instruction I can expect, then no chance.

This is not for beginners!!! This is one of the first courses I tried to take 3 years ago when I just started learning and it was so discouraging to have to quit it. Students cannot be expected to complete assignments with the tools they are taught in the lectures. This course is good for those with at least a year of casual experience with the language, and just want a guide on topics to learn. You will have to go and learn them somewhere else (forums, stackoverflow, etc.), but the course makes you learn them. It is for a more experienced user who knows how to find resources and learn on their own.

not the model of learning that is encouraging or sticks. hard for a student (even one who has a programming background) to sit through hours of slides explaining what the functions and definitions in the language do without a layer of use context upfront.
The content jumps from specific examples to unrelated specific definitions without carrying a sense of integrating the new knowledge with any past knowledge in the course. the whole course seems disjointed.
would have been much more effective as learning through examples and to be taught functions and definitions as they come up in problem solving.

The lectures and Swirl exercises are extremely easy to understand and follow, but then the assignments are incredibly complicated and difficult. The assignments ask for techniques that aren't focused on or even covered in the lectures. The tips offered by Al Warren in the Discussion forum make the assignments possible to do. Since the tips are so critical to understanding and completing the assignments, I think Al Warren's tips should be incorporated as part of the core course. This course needs more time to be covered in depth - it's a lot of ground to cover in just one month,

Course does not do a good job actually explaining R or training you on how to properly use it. The lectures go over the material very fast and you do not get much out of them, and then the assignments throw complex problems that are very difficult. You spend most of your time Googling to learn it, and I find that I would have learned R better if I just did that to start without this course. Maybe if you aren't new to R and have a programming background, it may not be so bad, but if you are new to R and not an experienced programmer, this is not the class to take to learn it.

Firstly, the level of assignments which are given are vey tough. This is due to the fact that the topics that are taught in the videos are of amateur level and the assignments are more than advanced level. No link between what is taught and what is asked. I am new to programming and i dont think person like me would recommend other to take this course. Even guys who has background in R would find this tough. I spent more time reading blogs and discussion forums than time spent on watching the course videos. WONT RECOMMEND TO OTHERS. STRONGLY UNSATISFIED.

i generally think the course needs a lot of improvement as after week 1 the assignments and quizzes don't seem to relate to the course content. we are at very different levels so a more gentle easing and explanation of ideas is necessary other than this apparent quantum leap from one stage to the next. i have had to do a different course else where and i am getting the sort of good introduction into the R language, its not practical to expect everyone to understand the ideas in 4 weeks.programming is hard enough as it is.

Would not reccomend for someone completely new to the program of R. Course is just an hour or more straight of videos covering an expansive number of topics and then a quiz that expects you to remember everything in the videos from hours ago. There should be exercises throughout the course to break in between the videos to reinforce concepts and help you learn as you go. I ended up spending much more time than need be trying to go back and figure out what video each concept needed for a question was covered in.

This course is outdated and the fact that they don't teach you essential libraries like diplyr, tidiverse and ggplot2, makes it harder thant it should be. Learning R should be fun and easier by learning this powerful libraries. Also the lectures are just plain slides with little to no value. They won't teach you the tools you would need to do your assignments so there is a huge gap in difficulty between the material of the courses and the assignments. This is a big struggle for newcomers into R.

Just use the swirl() package on R to learn - the lectures here go too much into irrelevant theory (why teach the history of R for a whole lecture, then only teach us in a minute how to read a file?) Debugging is also talked about at length, and then never tested nor mentioned again.
The assignments provided are also way more advanced than any of the quizzes or practices prepare you for. I spent more time looking up things on youtube, so you might as well learn for free there instead.

I somewhat resonate with the content expressed in the blog:
1, Not Beginner Friendly, better you are already in the position of Analytic field, Statistician,
2, Instructor read out the slide and I don't feel connection in learning, I resolved to other website for better understanding.
3, However, I would give credit to the only mentor (Len), who is really helping, explaining things in simple way.

Exceptionally bad course and worse instructor. I started this course with lots of interest in R and the way it is taught has made my interest much less now. Why is that?
the way videos are explained does not mean anything, It actually makes it harder to understand. the course assignments are very hard and one cannot do unless one learn on his own. Here is the catch the learn on your own is also not explained in the course. The only good thing about the course is the swirl().

Peer-graded Assignment: Programming Assignment 2: Lexical Scoping
In the peer-graded assignment is requested to completed an exercise using an operator never explained in the lectures, nor in the texbook, nor in the swirl package.
I don't like this learning method having very light lectures and heavy assignments, this is not the way I like learning as I find it very frustrating not to be able to complete the assignments using the material just learned.

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.

The course teaches random aspects of R, and you have to guess or look for information elsewhere to solve most of the assignments. The videos are often difficult to follow (you struggle to read what the tutor is typing) and there is no direct practical application. Surely, you need to know already a lot about R or you need to spend a lot of time on other resources to be able to complete the assignment. A lot of wasted time!

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.
