In this course you will learn how to program in R and how to use R for effective data analysis. You will learn how khổng lồ install and configure software necessary for a statistical programming environment & describe generic programming language concepts as they are implemented in a high-cấp độ statistical language. The course covers practical issues in statistical computing which includes programming in R, reading data inlớn R, accessing R packages, writing R functions, debugging, profiling R code, & organizing và 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 và cultivate their capacity for life-long learning, to lớn foster independent & original retìm kiếm, và lớn bring the benefits of discovery khổng lồ the world.


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


Welcome to Week 2 of R Programming. This week, we take the gloves off, và the lectures cover key topics like control structures and 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 và the debugging tools in R. These aspects of R make R useful for both interactive work & writing longer code, and so they are commonly used in practice.

This week covers how khổng lồ 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 and lớn 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 sầu is the most useful function in R.


"R Programming" forces you lớn dive sầu in deep. These skills serve as a strong basis for the rest of the data science specialization. Material is in depth, but presented clearly. Highly recommended!


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.


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 khổng lồ piông chồng up in this class. Assignments were a challenge, but satisfying lớn tackle.


Access khổng lồ lectures & assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for không tính tiền. To access graded assignments and khổng lồ earn a Certificate, you will need to lớn purchase the Certificate experience, during or after your audit. If you don't see the audit option:

The course may not offer an audit option. You can try a Free 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, and get a final grade. This also means that you will not be able lớn purchase a Certificate experience.
