学生对 约翰霍普金斯大学 提供的 The R Programming Environment 的评价和反馈

I liked the swirl() package a lot, made me jump into writing codes into RStudio straight away. My only wish was to have some videos that would push me further

The whole course was easy to follow except for the last questions of the last exam where the merged data set results into a null data frame after filtering.

I like the swirl exercises, but found the text lessons to be very short. Overall, good but I hope some video will be given in future modules.

The Swirl interactive course materials are really helpful for hand-on practice in R-studio. Learned a lot of R fundamentals. Recommended.

very well, structure, the quiz was admirably hard, but satisfying to work through and solve. you made me think outside the box, excellent

It is a very good course for new learners. However, it could be better if there is a R script writing the right code for the final quiz.

Course is good. However, some of the packages discussed in the examples, such as ggplot etc. should be discussed in more detail.

It is a very good course. I learned a lot. The only thing I wish I had it here is the videos rather than lots of pages to read.

Can be vastly improved by making it more student friendly and giving more tougher practice exercises to tackle to assignments

Very interactive and easy to follow course. However, the quiz materials are kind of confusing and still have some errors.

This is a good introduction to R but I do wonder if there could be a little more content, particularly in week 4.

The last quiz is super hard and makes you feel a bit unprepared. But overall I learned a lot from this course

Some good functional R training but really missed the videos like in the Data Science specialization

I think that the explanation of the material should be adopted to people that are not programmers

A very nice introduction to the R programming environment. I learned a lot and it was fun to do!

It is a good introductory course but the description of assignments could be more elaborate.

This was a quick an relevant intro to the getting data and conducting basic manipulations

I found that the course was a helpful introduction to the R programming environment.

Good content, a lot of work loaded in the quiz of the last week, beware of this.

Could have been better. Expected some interaction/videos from the mentors.

W​eek 4 assignment is broken. Otherwise thank you for the course !

This is what they don't teach you at university. Very good course.

It's a tough course for the beginners in R programming language.

Good lessons but wish there was more lectures by the professors.

Learned a lot through both lecture notes and swirl package.
