Excellent subject matter. 4 stars instead of 5 is only because there was no video. I love the videos in the other courses in this track, since I am an auditory learner.

This course covers advanced topics in R programming that are necessary for developing powerful, robust, and reusable data science tools. Topics covered include functional programming in R, robust error handling, object oriented programming, profiling and benchmarking, debugging, and proper design of functions. Upon completing this course you will be able to identify and abstract common data analysis tasks and to encapsulate them in user-facing functions. Because every data science environment encounters unique data challenges, there is always a need to develop custom software specific to your organization’s mission. You will also be able to define new data types in R and to develop a universe of functionality specific to those data types to enable cleaner execution of data science tasks and stronger reusability within a team.

The last assignment did take a while but worth it. Really appreciate for proving such a well-organized course.

It is a good course that forced me to understand the s3 and s4 object of R and have gained an appreciation of "methods belonging to functions not belonging to objects".
FZ
Very useful, I considered myself quite an advanced R user, but this class raised the level, especially with the R as OOB part. Good investment if you are not a beginner.
CC
More advanced, challenging course. Still, enjoyable and enlightening. Mentoring on this course is really helpful too!
PS
Awesome course! Learned a lot! It is mandatory if you would like to become an experienced R user, not just programmer!
SS
Great course but would prefer more video lectures versus text based lectures. Otherwise, a great course to help build out the foundations of R programming.
XZ
This course does help me a lot in learning R OOP programming as a beginner. I think both FP and OOP course projects are very well-designed! Thanks!
NN
That was exactly what I was looking for - first steprs In functional programming with perfect explanations and nice tasks via R :)
RH
The last problem is unnecessarily difficult with little related teaching and learning material provided. Otherwise, the course is certainly well worth taking.
JS
The final homework assignment is tough if you are a newcomer to R. It is sink or swim time. Worth it if you can get through it.

Great course! I gained a more in depth understanding of R and it's underlying structure. I did think there could more explanation given to object oriented programming R.
