ジョンズ・ホプキンズ大学(Johns Hopkins University) による Rプログラミング の受講者のレビューおよびフィードバック



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....

"R Programming" forces you to dive in deep.\n\nThese skills serve as a strong basis for the rest of the data science specialization.\n\nMaterial is in depth, but presented clearly. Highly recommended!

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.

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!

Excelente opportunity to learn a lot. The course is very well prepared introduce you to R programing. Dont feel bad if you dont get it at te first moment. It will be a process of leaning worth trying

This is an excellent course but be warned, the programming assignments are difficult. If you do not have any coding experience, the assignments may be a bit challenging for you. But with the help of the internet and Github, you can complete them with no problems. The course content is great. All the videos and information are for beginners and are very helpful. The best part of the course was the swirl exercises it had you complete in R. Swirl exercises acquitted you with the programming needed for success in R. Overall it is a great course. Just understand that the programming assignments can be challenging for new timers.

I learnt a lot, but most assignments required me to look a lot of stuff up outside of the course. They say they have done this deliberately to encourage "hacker mentality". I agree that we need to learn how to cope on our own, but it ends up taking up hours of your time and seems like a pointless lesson. One reason for doing a course like this is so that you can have access to consolidated and trusted learning materials, which was not really provided. Having said that, the assignments are a good way to push yourself to learn R. But most of what you need to do the assignments will not be provided within the course.

The assignments were way beyond the scope of what was taught in the lectures.

Assignments are hard compared to the content

Programming assignments are very hard (and in some cases irrelevant) based on the material presented and topics discussed

Gave to little instruction and expected the assignments to be completed based on very little instruction

Honestly, I'm very disappointed with this course. The content taught in this course is not in accordance with the assignments. It is like someone taught to be a builder and asked to build the Brooklyn Bridge ... Not fair at all.

If you are going to ask to build a bridge, teach me how. If you teach me how to be a builder ask me for a wall, not a bridge.

If I wanted to learn from outside source and "hack" my way through understanding, I would not be paying money for this course. I am paying money as I expect a smooth introduction and summary to the topic which it is not. I have taken classes in SQL and python on courser. Those were of better quality. I think this R class is one of the worst.

Damn near worthless. The course material has significant gaps of information. The programming assignments require knowledge that isn't presented in the course. I had to Google my way through this entire course. I would not recommend it.

Brilliant content!! Practice exercises really help you evaluate yourself. A little knowledge of R programming before this course is helpful as that might help understand the slides better. Though it is not mandatory but one can still utilize free resources available online to build the basic knowledge. Also, if you have prior experience with any programming language, that'll be very helpful. Would highly recommend this course.

This was very engaging, however, the level of expectation and effort needed is much greater than course 1 - ToolBox.

This is perhaps the best course on R Programming designed for a small duration.

The only feedback I have is that they should try to incorporate more examples (simple real world ones would be great) when explaining concepts in R, because otherwise it is quite dry. The things you learn in the individual lectures give you a very basic idea of the functionality without much insight on *why* its important or *how* it can be applied...I found most of my solutions/answers by googling and using swirl a bunch of times. However it is rewarding if you power through it and have A LOT of patience, especially if you are a beginner with no background in programming (like myself).

This course is tough if you have zero background in programming. I struggled alots especially in the last assignment.

I learned something, of course, in this course. But without previous experience in data science, I found it OK to understand the lectures, but always got lost in the coding assignments. I tried to finish it on my own, but it turns out I have to search everything online. I felt that there's a big gap between lectures and assignments.

very good course but you need much more time then announced to finish the assignments

Needs to be more interactive

I think for a MOOC, this course could have used the power of video a lot more, listening to the videos that are basically voice over a slide , wasn't helpful at all, and if it wasn't for the book, I wouldn't learn anything.... if the videos were more illustrative and visual to explain certain concepts , that would have been much better

Very poor material. Very theoric, no interaction, interesting applications or examples, and very boring lectures.

The material is very trivial, without real applications.

The assessments were useful but in some cases they were not related with the topic.
