In this course you will learn how khổng lồ program in R and how to use R for effective data analysis. You will learn how lớn install and configure software necessary for a statistical programming environment và 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, & organizing and commenting R code. Topics in statistical data analysis will provide working examples.

The mission of The Johns Hopkins University is khổng lồ educate its students & cultivate their capacity for life-long learning, to lớn foster independent and original research, & to bring the benefits of discovery lớn the world.


This week covers the basics lớn get you started up with R. The Background Materials lesson contains information about course mechanics và some videos on installing R. The Week 1 videos cover the history of R & S, go over the basic data types in R, & describe the functions for reading & writing data. I recommend that you watch the videos in the listed order, but watching the videos out of order isn't going to lớn ruin the story.


Welcome khổng lồ Week 2 of R Programming. This week, we take the gloves off, & the lectures cover key topics lượt thích control structures & functions. We also introduce the first programming assignment for the course, which is due at the end of the week.


We have now entered the third week of R Programming, which also marks the halfway point. The lectures this week cover loop functions & the debugging tools in R. These aspects of R make R useful for both interactive work and writing longer code, and so they are commonly used in practice.

This week covers how to lớn simulate data in R, which serves as the basis for doing simulation studies. We also cover the profiler in R which lets you collect detailed information on how your R functions are running và to identify bottlenecks that can be addressed. The profiler is a key tool in helping you optimize your programs. Finally, we cover the str function, which I personally believe is the most useful function in R.


A great introduction to lớn slightly more complicated R programming. Basic concepts covered well and it builds nicely to the point where you feel like you can apply your knowledge to real world examples


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 lớn tackle.


Nice course but it would be better if more liên kết to this course & exercises were added for students to be able to lớn have more practices not only with swirl ( ) but also with trustable third parties.


The course was a wonderful introduction khổng lồ R, though I felt the programming projects were lacking a bit in terms of direction. Definitely go through the swirl exercises lớn help reinforce everything!


Access lớn lectures và assignments depends on your type of enrollment. If you take a course in audit mode, you will be able khổng lồ see most course materials for free. Lớn access graded assignments và to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the phân tích và đo lường option:

The course may not offer an audit option. You can try a không lấy phí Trial instead, or apply for Financial Aid.The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, và get a final grade. This also means that you will not be able to purchase a Certificate experience.
