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.

NIce course and good exercises. I'd suggest better and more explanation on scoping rules and examples on updating global variables in a loop or a local section. Thanks!

A great series of introductory courses to R programming, data science and statistics. I enjoyed taking about 6 of the 8 of these courses before I had to take a break.

R Programming is a good, dicdatic and comprehensive course on R. It teaches you how to perform the main operations, subset objects, write functions and deal with data.

I was using R in my thesis but back then I did not understand well the R as a language. This course provide me the basic and intermediate skill to do programming in R.

Very satisfied with the course layout and material. The opportunity to learn both through videos and through Swirl assignments is very helpful for reinforcing lessons.

This is a crash course into R-Programming. If you have never did any programming this course will be a challenge! But it is a good way to get going with R-programming.

This is a very good introduction to R. The material is good and this works well as a introduction to R if you have either high interest or some programming experience.

Worth it. The final assignment was a great challenge, the course seems to cover some good concepts of R, and provide a good base for those looking to learn even more.

I really liked the course, I learned new things that I did not know.

I will continue with the rest of the courses in this series

Thank you Johns Hopkins University

This course was exceptionally informational and it did upskill and that's saying something because I had applied to a lot of courses but this gave me what I needed

Really useful course. I strongly recommend to spend time on the programming exercises, specially is is long time since your last programming task (e.g. > 10 years)

I had experience with R in a class at my university, and I learned a lot in this course that my class didn't cover. The assignments were more challenging as well.

The lectures, swirl modules, and assignments had very high synergy for a multi-faceted learning experience. The pinned posts in the forums were extremely helpful.

The level increases very very fast. For people starting from scratch (as me) will take the to complete the assignments. Challenging, but overall of great quality!

Exellent for beginner.

I literally didn't know anything about R, and was not familiar with programming.

This course gave me a step for advanced data programming.
