Another great course! I'm really glad there was so much support to help me get started on the class posts. PS, I think I'm in love with the ddply function.

This course is absolutely fantstic education. More practice tasks will make it better in my opinion.

This course is very enlightening. The techniques demonstrated in this course are critical for gathering raw data from various sources and turning it into useful data for analysis.

Nice Course

I really really loved this course. Some of courses before were outdated because there are lots of changes in packages or others. However, materials in this course were not changed that much.

Very Informative course.

Great course to introduce you to the various methods of loading and processing data in R.

The course is an excellent introduction to the dplyr package and string manipulation in r. I thought the assignment at the end of the course was a little vague and hard to understand

Really helped me learn the different sources of acquiring data into R and methods to transform data into tidy data

This course is one another step forward towards my data science specialization. I'm really enjoying my study about data Science.

nice course for the cleaning data using R,

Coursera is very practical and I am ready to continue to study more courses.

I am very happy to go through this subject not because of the certification but I learned the steps to import and clean the data. Although this subject is no rocket science, a lot of the data available on the web will require the knowledge that I learned in this subject to enhance the integrity of the data that anyone can download from the web.

The level of difficulty of this course is on par with R Programming. For the first time in the specialization you will find yourself scouring the forum for tips and suggestions on how to proceed when you get stuck in the quizzes. Fortunately, the mentors are really helpful when it comes to answering questions or clearing obscurities. I really liked this course, in fact much more than R Programming.

Great course for hands-on data munching

It gave me an overview of how to getting and cleaning data.The course is best suited for anyone who is a novice in data science

A little bit hard for newbie

Good overview of what it means to get and clean your own data. Really enjoyed the final project as it challenged you to, with minimal guidance, think through what a tidy dataset really means, and figure out how to make that happen with the dataset you are provided.

Super useful, there are so many raw data in the practical world, which are needed to be cleaned, so that the analysts and other people can easily get information from data.

good intro to R

It was challanging and informative.

best course ever

This is a very complete course. It covers the basics of what you have to know to adquire data from different sources and filter that data to be used in further steps of data analysis. It offered great notions on Data Mining also.

Very good.

Congratulations!

Good course
