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....

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.

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.

Great course to get the basics of R and have some hands-on experience with writting functions, profiling code, basics of statistic simulations as well as data frames handling.

I will be glad if we have a few solved examples for assignments. It would set up a good base before we get a programming assignment. I had a hard time figuring out everything.

The material provided should be more simplified as it is not up to the mark to understand .

Until and unless one does the swirl pakage he/she cannot understand the basics well

Very well structured and interesting course! Minus 1 star as the second assignment introduces some new concepts which were not in the lecture material or practice exercises

Good course but you will need to Google a lot, have some prior knowledge in the programming area, and dig through the forums if you want to pass the programming assingnments

Great on line course

quizzes are reasonable and assignments are not easy for the beginner which took decent amount of time to finish. overall great experience for learning R.

It is a good course for learning R.

Every topic is covered, and you get the gist of it.

The assignments are harder than the course.

You can not become an expert by using this.

Rewarding but at the same time challenging for programmers who are relatively raw, it will take a while to understand the nuts and bolts of how to estimate the assignments.

It's a good course for those who want to start programming in the R language. I just think the classes could be more explanatory and should contain more practical examples.

Learned a great deal of programming, since I have never done anything like that before. However, the estimated durations per module were quite off for me in both directions

Very good course, however I find some of the chosen covered topic maybe too specialized (ie lexical scoping for example)...however maybe it will make more sense with time.

The homework cannot be completed using what I learned from the class and the recommended book, especially the project assignment from week3. But overall, I learned a lot.

The course was nice, specially 'swirl' is a great tool to learn and catch back.

I do have some issues with assignments which were sometimes very difficult to understand.

The course is great!

The only problem that I had as a complete beginner to R programming, is that the assignments were a level harder compared to what the course teaches.

The swirl programming exercises are sufficient and helpful but the assignments are too hard. It would be better if a (more detailed) skeleton is provided for each task.

Very tough. The lectures diverge from the quizzes and swirl examples but all in all were helpful. Would love recommended book chapters to read to round out the course.

This is a great way to learn R programming and covers really important stuff. However, the programming assignments weren't clear and requires more examples and details.

Interesting outcome (especially for assignments), but the course material could be better and more appealing (instructor basically reads his slides and stutters a lot).

A good introduction to R. The practical assignments with Swirl will help a lot for those new into programming. I recommend to take additional introductory courses in R.

Very nice course. It covers the most important aspects and has good documentation. Is important to dedicate more time to get to know properly the tool and the language.

Muy buen curso pero debes estudiar mucho por tu cuenta, la dificultad de las tareas de programación está muy desproporcionada en función de lo que estudias en el curso

Difficulty of Programming assignments was much higher than anything else in the course. Took a lot of "hacker" mentality to complete them...but maybe that's the point!

The best part was the Swirl package to practice. But I think it would be better if you provide more to practice because R is different than other languages like JAVA.

Pretty good coverage of statistics and dataframes in R. Would consider this worth the money I paid for it and I've used R in the past. Newbies will definitely benefit!

Good course to get started and get you comfortable with manipulating data in R. However, does not cover object oriented programming, pivot tables or advanced plotting.
