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....



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!


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

創建者 Alexandra G


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

創建者 Veerendra A


it was too fast for me and i was expecting to study R programming from scratch..and many things were very fast.

創建者 Duncan P


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

創建者 George J


The instructions were not satisfactory, and there is a large gap between the assignment and the skills taught.

創建者 Ben W


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

創建者 Tristan I


Fix the assignments so they match the course content. This is unfair to the people who pay for this service.

創建者 Casey L B


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

創建者 Jonathan N


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

創建者 Rishi R


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

創建者 Joan S


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

創建者 Jostein B


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

創建者 Juan M O


Gap between the theory and the practical assignment is huge. For a beginner is not an option!

創建者 p a t


This course is not for beginner. If you look for beginner course for R, look else where.



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

The assignment is too hard. There is a big gap between the assignment and the lecture

創建者 Stéphane P


It's good introduction, but the assignment are rather poor. Not worth paying for it

創建者 Thomas Y


Doesn't teach many functions that are related to how to solve the question at hand

創建者 Avdesh s


In Lectures rate of speech is really fast and in some presentations are not clear

創建者 L. R B


There is a disconnect between the video lectures and the assignments/quizzes.

創建者 Adanna G A


Assignments not always in line with lecture.

Material is above beginner level.

創建者 Gamze M


the assignments were very hard to understand. the course videos were poor.

創建者 Mohd Z A K


They taught lower-level programming and assignments are very high-level.

創建者 MD. A Z


Lessons that were tought had almost nothing to do with the assignments

創建者 DarrenWu


Why should I waste my time listening to someone reading a book to me...
