About the Course

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....

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.

"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!

Good content overall but programming assignment requires deeper insights into syntax that were not covered

Assignments are a huge step up in difficulty compared to lectures. It is like there are lectures missing.

The programming assignments were way too difficult compared with the material presented in the same week.

I felt some assignment required more knowledge than the course had offered. Overall this is a good course

its good and still more programming problems can be discussed to ease the learners to dive interest in R.

the presentations are very hard to follow, it requires a lot of extra time reading the professor's book

The lectures were a bit hard to follow and the assignments were way harder than the topics in lectures

Much of the material is learned via googling. Do not look to the course videos to be enough to go on.

Large disconnect between course content and assignments given. Otherwise a good learning experience.

examples are way too easy compared to the disproportionate difficulty of the programming assignments

While the lessons are good, there is a large difficulty spike with a few of the course assignments.

I wish there were more in-depth exercises at an intermediate level before what we got in the exams.

Too big the gap between lectures and assignments. Only partially filled by the task of the mentors.

There seem to be a big gap on what was taught and was was given in the quizes. Overall it was okay.

Assignments are far more challenging than they should be. Course content is good introductory to R.

Could do a better job of teaching more of the fundamentals involved in the Programming Assignments.

The gap between teachings and assignment is quite large. This is definitely not beginner-friendly.

The pace of talking of some of the intutor is too fast, if slow down a little bit, will be better.

there is a wide gap between the videos, practice assignments and completing the required projects.

It was very difficult for me to follow the exercises, since I don't have a programming background.

Some good information, and a good course platform, but I didn't feel all the parts fit together.

Way too wide a gulf between the material in lectures and practice exercises and the evaluations.

The first course is better - provide students an alternative learning method aside from videos.

The homework is more harder than what I learned. The errors in speaking made me uncomfortable.
