課程概述

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....

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.

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.

The level was a little bit high to be an introduction. This specialization should have 2 R programming courses, instead of the introduction that is very simple compering with the second one... Anyway, I have learnt a lot and I am quite satisfaied.

The Programming Assignments (specially the Programming Assignment Week-4) were quite difficult and not self explanatory ... Although we learned some topics during the course, the entire set of tools needed to complete the Assignment was not given.

There is a big leap in the skill level between what is needed to complete the homework assignments and what is needed to complete the final programming assignments. I think more focus is needed on the structure and technical design of a function.

Lectures were rather weak - did not adequately prepare learners for homework.

Also, googling issues often led to others posting homework online asking for help. I would exit those sites, but it appears it is time to start offering some updated HW.

I felt that the programming assignments were not explained well enough, things like different syntax that wasn't explained and such. If the class required a lot of outside research not included in the class, they should mention that more clearly.

It would be better if it was more interactive. The videos aren't very helpful for a beginner programmer, and the assignments are pretty challenging. I still feel like I learned something though, but mostly from swirl which is a pretty cool thing!

Everything begins slowly and everything is nicely explained at the beginning. But then suddenly the level of difficulty escalates ... for someone without any previous knowledge it is nearly impossible to finish the assignments independently ...

I have to say i learned a lot from this course, but the relevant between the course' videos and the assignment attached as follow is less. Even though i finished to watch every video, the process of finishing the programming assignment is hard.

A bit of a deep plunge if you've never coded before, yet too shallow to satisfactorily introduce someone skilled in other languages to the many peculiarities of R. I don't envy instructors trying to balance these two needs in such a short time.

总体上来说,学习这门课还是有收获的,比如能用R进行一些非常基础非常简单的统计,会小有成就感。

但是,这门课的确不适合如我这样的没有编程经验的人学习。首先,这门课的课程内容感觉安排的相当松散,感觉各周之间和各个lecture之间都很跳跃。课程里面的一些例子也比较复杂。其次,就像讨论区的一些人所评价的那样,这门课的作业难度确实很大,而且和授课内容相当脱节。基本上,认真听了所有的授课内容,完成QUIZ也不成问题,但是作业难度还是很够呛的。

PS, 只有我一个人很不习惯老师讲话距离麦太近了嘛!!

This course is very thorough, but I did not feel that the lessons often prepared me for the programming assignments. I found that I was frequently looking on the internet for additional resources and finding that I was definitely not alone.

The course material discusses basics and the quiz questions involve having to learn and implement much more than what is taught.

Taking a sample question(or something similar to what is asked for in the quiz) and explaining that will help.

Los ejercicios prácticos no entran a tanto detalle como sí lo hacen las evaluaciones y son bien fáciles. Mejorando eso (un swirl package u otro adicional) la experiencia sería mucho mejor y verdadera sentiría que aprendí bien el curso.

Course was good, but the material covered was at a fairly high level and done too quickly. This course could use some demos and since its a core foundation for the rest of the courses, maybe it should be a longer more in-depth program.

I thought this course varied pretty widely between the basic, building block nature of the videos and swirl exercises and the difficult assignments. I did not feel as though the curriculum set me up to be successful on the assignments.

Difficult course. Prior knowledge in programming clearly a big help to adequately follow course material. If no prior knowledge is had, then following the lectures swirl exercises and completing the assignments is quite a challenge.

The assignments were much tougher that the teaching material.The lecture dont even cover lots of things that are required to complete the assignments.The lectures need to include more contents for the students to solve assignments .

Course is quite interesting. Swirl is a very good platform for learning. Assignments while might seem difficult, can be tedious, but still able to complete.

If one has background on programming such as Matlab it will certainly help.

The course is excellent and cover many tasks that usually you perform with R. However, on my opinion assignments are not really focused on the topic of the classes, they are not really explained and above the grade of the classes.

Extremely hard programming assignments for people with little or no programming background. Even though these assignments were truly challenging and difficult to complete, the course complied with some of the proposed objectives.

The programming assignments are a great way to get your hands dirty with R, but this is not a course for someone without any prior programming experience, and I found the lectures didn't have much connection with the assignments.

There is a huge gap between the content taught in the lectures and what is tested in the assignments. Other than that, it is quite a good learning experience IF you have a decent amount of experience with programming beforehand.

Me ha gustado, pero creo que los vídeos serían mejores si se viera al instructor programando más a menudo, en lugar de solo teoría. Para las personas que no tenemos apenas experiencia en esto, resulta un poco difícil de seguir.

The course's program assignments could've been framed more clearly to understand better, especially the corr function in program assignment 2 and the last program assignment, overall the course was a good experience to learn R.

Very challenging course for a beginner with well designed assignments. Terrible lectures however. Most learning is self led using Youtube and Data Camp. The supporting material provided via the discussion forums is very useful.
