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....

"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!

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.

Assignments don't always align to the course content....

In terms of usefulness and coverage of this course, this really is just the basics of R.

for a beginner user the assignments were too difficult. there was a gap between the courses and the assignments. the swirl courses were helpful

Huge gap between programming assignment and lectures. Need to seek other resources to be able to solve/complete the programming assignment.

it is NOT for beginner, the student should have "more than average" in the programming languages, in order to get benefit from this course.

There's a huge gap between what is taught and what is expected in the assignments, the course is good but needs to be more comprehensive.

material is just not prepared with a beginner in mind. the assignments are too challenging for someone with little/ no coding experience

Great course. But to be frank it was the "Swirl" exercises that did 80% of the job. The lecture videos weren't at the level I expected

Lectures and exercises are very good. Somehow assignments are not related to the lectures or exercises. Assignments are too difficult.

Solid course overall only complaint is the programming assignments are a bit difficult to do based on what is taught in the lectures.

The main exam is to difficult. I feel there was a huge leap from theory to the actual finishing hospital function which was complex.

The last coding assignment was way beyond what was taught in the lectures, the syntax search eats up most of the assignment solving

Lectures and the homework are not quite relevant. The instructor explains so little on programming, but the assignment are tough.

Disconnect between lectures and assignments. requires significant amount of extra curricular research to succeed in assignments

Lectures were too quick at times and many of the assignments had little to nothing to do with what we were learning that week.

If you are beginner for R programming,I suggest don't enroll this course. This course is for someone who is experience in R

Seems outdated (content is 5 or 6 years old). Assignments are challenging as the videos and readings cover only the basics.

Very challenging assignments! You learn a lot. Please, give more complex exercices to prepare before the final assignment.

The course content is fine however, some assignments really surprised me. To the course presenter, keep up the good work.

Assignments are really usefull, but there is a lack of content relation between them and the content of the course itself

The video lectures were different and the assignments are very high level. Very difficult to understand the assignments.

Very hard to understand. Needs either really huge amount of time to self-learn, or familiarity with programming language

The course lecture was ok, Swirl was pretty good. The assignment was confusing and the instructions were not very clear.

Course lectures are good but course assignments and quizzes are sometimes too difficult and not covered in the lessons.

Not practical for beginners. Probably useful if you already have extensive experience with other programming languages.

Huge gap between theory and programming assignments, however quizzes are interesting and require some time to complete.
