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!

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.

Excelente curso introductorio, considere que la tareas son de mayor nivel que las lecturas.

Tendrás que investigar un poco más por tu cuenta para resolver las tareas.

Good one for a beginner. The assignments requires self study from the internet as the material isn't at par with the assignments, they've slightly higher difficulty.

Good. But may need to check whether all the information in the lectures are updated, such as all the arguments in the function may not work with the latest package.

Not an easy one, but for experienced developer who wants to learn a new language, and all help provided (forum, examples etc.) it shouldn't be too hard to complete.

You have to put in a lot of efforts on your own.

Sir Roger D Peng explained too short details. Then again, a good start to understand functions and programming in R

The projects are very challenging for those who have no experience working with R. The syntax seems similar to C++ but the nuances of the code are hard for newbies

Tough, but the excersizes are really usefull and make you get a feel for R. I wouldn't recommend this for a beginner who has never had any programming experience.

I believe it is a great course, but its pretty hard to catch up how to code if u dont have basics of general coding: logical thinking and problem solving aproach.

The assignements are excellent for learning. however, the last assignment for programming might be too difficult for total beginners. need to put in extra effort.

it was a little confusing where to submit and how to submit the week 3 assignment. I was to learn R not a site to collaborate on R. Okay course though. Cheers

A good class. Some of the concepts required a good deal of research to understand and use, but that research is really the heart of modern development anyway.

I feel this course is too difficult ,The requirements for learners are too high, and the explanation is too shallow. but i still learn a lot from this course.

Decent course. Material is a bit stale, aka questions are common on several sites. The course was not really challenging, though i did learn a few new tricks.

The pace of the course can be increased. Unnecessary videos present. Time is very valuable. Fitting max useful information in less time in the most important.

I have achieved my objectives of learning the basics of R through this course. Only I wish there were little bit more information on the plots... ggplot2 etc.

The course isn't bad, but you need to be aware that it gets quite difficult at the 2nd week. I had to stop it because the assignment was way to difficult.

faculty is quite quick...must be clear and understandable to the students. pause and resume this happened quite often....but the overall process is good ...

Good course, at the end a bit difficult as you have to program your own functions. For a person with no R knowledge at all would be very difficult to pass.

Decent class with good programming assignments. I wish there had been more examples of actually writing code in the lectures, but that is my only complaint.

Only problem was the large gap between the assignments and lectures. Swirl exercises should not be optional as they are the most helpful part of the course.

The course is fun coz of swirl. But the tutorial videos aren't very informative. sometimes it's not so clear. I think improvement can be made at that area.

Designed for everyone who wants to know the basics of R along with introduction on how to play with large amounts of data and get the statistics out of it.

Good course. Would have been great to see a few more examples to explain concepts but otherwise great flow and good support through swirl coding practices.

You might consider splitting the quiz in week 1 into a quiz over the lecture material and a quiz over the programming assignment. Similar to weeks 2 and 4

The lectures were very well-explained & detailed but the assignments were very hard to solve. Overall this was a quite challenging course and I loved it .
