課程概述

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.

I got a lot of out of it, but I felt like the programming assignments were of major-league difficulty when I'd been equipped for the minors. That said, the lectures are very clear and I learned a lot.

Quiz and especially assignments were poorly written. Spelling mistakes in slides is simply unacceptable in high-level academia, in my opinion. Especially for a course designed for a global audience.

The swirl() exercises are a nice tough, the videos are dry and stale, the exercises WAY more difficult than the material covered by the videos. A tough slog … but that's one way to learn, I guess.

Overall good course. It could explain things in more detail and be more practical in the teaching method. Also, they could evaluate better what they actually teach regarding the assignments.

The overall structure of course is good for Beginners but the programming exercises are too advanced as compared to what is taught in this course. Kindly, tone down the level of assignments.

I found that there was a huge gap between the level of coding demonstrated in the videos when compared to what was required to complete the assignments. I liked the content delivery methods.

There is major gap in the course syllabus and the assignment tasks. I have to always spend hours on the internet to accomplish my assignment goals.It would be great if this gap is bridged.

The assignments are moderate in difficulty. However, they are often not related to the lectures from the same week. At the same time, a lot of topics covered in lectures were not applied.

nice course, nevertheless it was way too challenging. I believe this course would be much better if it would be a 12-week course instead of 4, and it would go slower through the material.

I am finding it very difficult to follow, feel like I am missing a chunk of information. However I will say that everyone else seems to be managing so it is probably me missing something

no comment with the content, however, as being slightly obssessive, the way of the lecturer uses when talking, and the sounds of the lecturer, just made me only want to see the text.

OK as introduction to R, the course works through data structures, functions, etc. Swirl exercises are helpful. Assignments involving basic data analysis start to get interesting.

The difficulty of the assignments increases fairly dramatically week over week. It might be more productive to scale this content more gently by dividing it into a two-part course?

In some cases I felt the course lecture (video) was bit tough to understand and few things could have been explained better. The Swirl complemented and filled most of these gaps.

poorly thought out course. Assignment does not evaluate what you learn from the lecture videos but rather explores new topic. Nonetheless, it still teaches the basic R programming

The assignments where not properly designed. Few of the lectures on loop functions could have been better explained. Swirl assignments where good but where not a part of grading.

Mostly a good course. However, the synchronization wasn't good with the course material and quiz/assignments. All of the required skills were not covered in the video lectures.

This course will teach you a lot but it is very difficult. The programming assignments are very challenging. I would not recommend this for someone who has never used R before.

Content covered is great. Assignments take a very large leap in material from the videos. I would recommend making swirl lessons required and adjusting difficulty accordingly

some knowledge needed in the programming assignment is not covered in the lecture, my friend and I spent so many hours searching around and debugging in order to figure it out

The course is challenging and the exams use real-world data.

The sequence of the course is not linear, the exams are too difficult compared to the material covered in classes.

I'm not saying R Programming has to be a gripping subject, but this course is pretty dull. The value of good teaching methods is often underrated in transferring knowledge.

創建者 Iain L

Useful content, but the assignments often don't consolidate what's been covered (i.e. aren't summative), instead introducing new topics which requires independent reading.

Le cours en lui-même ainsi que l'entrainement sur swirl sont bien réalisés. En revanche, les devoirs à rendre sont à un niveau bien en dessus de ce qui nous est présenté.

Good course overall but assignments have too little guidance in how they should be completed and can its easier to use material from future lessons to solve the problems
