À propos du cours

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....

Brilliant course. Loved Week 4 for OOP. This was really new for me and would love to have been able to see its application in real world examples to better cement the concepts.

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.

Great acceleration of the specialization compared to the first course. It covers modern approaches (as map-reduce-filter implementation in purrr), nicely explains debugging, benchmarking, OOP etc. I would recommend this as a kick starter for more advanced R programming.

I find that some of the course materials are not sufficient for the learners to understand the concept in R programming and complete the assignment. The course could be improved by including more examples and hands-on exercises.

I think, as the last week, the first 3 weeks should have something more complicated to do. The

complexity level of the exercises grows exponentially on the last week of the course.

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.

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.

the last peer review problem is much too hard for what I learned from the course material, if there is a more specific instruction for the assignment will be better.

The last problem is unnecessarily difficult with little related teaching and learning material provided. Otherwise, the course is certainly well worth taking.

If this course could recheck the material and offer some mentors/monitors to provide hints/tips in more asked topics (like a FAQ) it would be excellent

It's really good practice for using R as a functional language, but

no video lectures makes student feel bored

Good course but the part of OOP is a little too simple, some extra in class exercises could improve this.

Good Course! But focus should be more on OOPs Concepts through video lectures to better understand it.

I wish the assignments could be a mix of teacher and peer graded.

need more information about how to complete de week one

Need to have more visual approach to the course.

The forum for the final week has everyone asking each other to review their assignment because it doesn't get done. There might be something broken with the system here.

With regards to content, it would probably be better to just read Hadley Wickham's "Advanced R", and "R Packages", and "ggplot2" for this whole specialisation. In fact, I wouldn't be surprised if the material for the specialisation was just taken from these 3 and "R for Data Science", and then compressed to make it easier to digest in 4 week chunks.

It was ok, so I'll give it 3*. But there could've been more material here. It didn't feel "Advanced" to me.

Like the first module in the specialty, this one is riddled with typos. Some of the examples could have been a little more detailed or just more examples given. Again, some of the swirl assignments were just walking through the readings. The topics covered here are more advanced, but I feel like I just read an online tutorial and didn't really take a "class".

par Chao G

The quality and the difficulty of this course is really good. It would even be better if more advanced topics are covered in details (e.g. AST, substitute function). However, the peer review assignment could be a pain since sometimes you do not get helpful feedback. Occasionally there are not even enough students to grade your assignment.

par Rebecca G

This course was not great. Almost all of the information is a screen scrape from a book and peer-evaluation, so you may be better off just getting the book and going through it. The mentors very occasionally participated, the authors never. The assignments are poorly written and missing too much detail.

par Min P

This feels like self-study rather than being taught.

Despite the reading material is self-contained and well-organized, peer-graded assignment doesn't look good, though.

Getting attention for it to be reviewed is a hassle.

WIsh there were more assignments. The final project was the only assignment in the course. Object-oriented programming in R requires more than a single assignment to grasp- even at a superficial level.

To complete this course you have to go back and forth for the basic. Also the final assignment is bit ambiguous, more clarity is required.
