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.

Really great course with good lectures. The assignments are harder than what you'e expect from the lectures but guess that's part of the learning experience.

Great explanation and progression enabled me to gain confidence in R programming. I had the opportunity to gain a new skill during this quarantine period :)

I found this course challenging but very interesting and useful! Still in the dark mostly about the true purpose of lexical scoping in practical situations.

Swirl exercises are simply brilliant! Perhaps you can add more challenging problems

The assignments push you to research, which I think is a major plus point

Great course! R syntax can be tricky, and it often took a bit of googling and experimentation to complete the exercises. But I also learned a lot doing so.

I am working as BI and using R almost every day.Thank you for this course.

I can say that it very powerful tool for data analysis, especially big datasets.

This class was really good. Coincidentally I was struggling with this type of code. The case is challenging but very well delivered. The material is great.

Excellent course. May be difficult for individuals with little to no programming experience. The programming assignments are fun and will teach you a lot!

Really good course, and structured in a way that you have to do a lot of thinking, reading, and research for yourself - forcing you to learn and explore.

high level teachers , and well-organized course, in a pedagogic way. Understandable for non-specialists, requires a significant amount of personnal work.

Really quite a detailed introductory course on R. For those wanting to get a kick-start this would be the perfect course for the cause without any doubt

A good course to gain more experience in programming with R. The assignments are of reasonable size, and expand on the basics presented in the Toolbox.

Challenging. Its a plus if you have a background on PHP, Python, and Java and not just SAS and SPSS. Otherwise, it would be a steep learning curve in R.

La primera vez que lo tome significo un impulso en mi carrera profesional; efectivamente iniciandome como un programador en R, y no solo como un usuario

Great course for beginners! Informative, well-structured and straightforward. The "SWIRL" exercises and the introduction to GitHub are also very useful.

I encountered some difficulties in the process, but through getting help, I managed to survive and learn the course. It's been a worthwhile experience.

Awesome, but you need to put hard work into it if you're completely new to R. Assignment 3 will kick your butt and you need to be ready for it; revise!
