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.

There is a wide gap between the lectures and the practice. Its clear that the video material is completely inadequate and insufficient for the course. A poor introduction to programming.

The jump from the lecture material to the assignments was way too much. In order to complete the assignments, one needs to spend lots of time learning things not covered in the course.

Week 2 is an unreasonably difficult jump from Week 1. This course's beginner friendly lectures do not align with the level of understanding needed to complete the assignments.

This course was labelled as for beginners but was in no way for beginners. The instructors were completely absent. The course material did not reflect the assignments at all.

Very hard for a beginner. Lacks the slow build up I needed. Missing an explanation about a comma cost me about 4 hours. The assignments are brutal which encourages cheating.

homework was poorly structured and not adequately discussed in the lecture videos. Had to dig through several buried links to make any progress on the homework assignments.

It's too time consuming, not for a newbie. The classes are pointless, cause they are pretty easy and then the homework is ULTRA-DIFFICULT, classes are pointless.

R training and coding is not good. Explanation is good but assignments are very different and one needs to self learn a lot of R coding by themselves.

Lecturer is very poor, explains very little and the assignments he give have no connection whatsoever to what was taught. waste of money and energy

Lectures are very boring and designed in a weird way. He is simply reading the book that he wrote and no real practice was ever done.

Not the best course for beginners. Too much theory and no implementation. Also the assignments were impossible for a beginner.

Not for new programmers. The lecture material is also not logically organized and does not correspond to the assignments.

R tutorials and assignments are great - however, had to spend more time figuring out Git than I spent on R assignments...

They don't give enough inputs and instructions to complete the assignments, unless they could offer addicional material.

I found the jump in difficulty for the first assignment too great. This seems to be a view reflected elsewhere.

This course was so convoluted and not practical that it made me lose complete interest in the specialization.

This course presumes you are a programmer to begin with. I tried to take the class to learn how to program.

Assignments do not match up well with the lessons and the lessons are BAD. They are not educational.

Too much of a jump from the previous course. Exercises much too complex relative to the lessons.

You can't do assignments using the lecture materials. Need A LOT of time to finish this course.

There is a huge disconnect between the lectures and what is asked in the homework assignments.

Actually I feel like i'm reading the instruction manual without knowing useful skills
