Amazing course! Even after a few years using R in a daily basis, I still learned quite a bit of new / useful information.

Great course covering a wide range of data types likely to be encountered in the field of data science. Well explained.

Really great class. I found the lectures easy to follow. The quizzes and homework helped me master the course material.

I believe it was a very good course ,challenging and interesting. As a beginner in Data Science and R I learned a lot.

A good course, which helped me understand how to get data off the web and from other sources, and improved my R skills

This course is very interesting, useful and practical

I appreciate for all of efforts of my professors in this course

Very fundamental things that all data scientist must learn. You will know how useful of data.table and dplyr package.

Interesting, challenging course. Opened lots of questions to the topic and gave a good direction to find the answers.

Entrega conceptos y herramientas útiles. El material es de buena calidad y es presentado de una forma bastante clara.

Very simple and introductory course that teaches the concepts really well. Forms a brilliant specialization course.

Great coverage of useful R libraries for retrieving and tidying up data, and difficult but valuable course project.

Very good class for a beginner. Helps become more comfortable with R programming and aspects of getting data into R

Challenging course for working professionals from time perspective but very educative and useful. I learned a lot.

A must take course for data science carrer... Very good concept explaination with really good hands on with Swirl.

Excellent survey of data cleaning methods, good grounding in tidyverse tools, builds nicely on previous 2 courses.

was a hard module for whose isn't a programmer, but was well done structureted to easy learning with hard studying

Many tricks and tips tools, many good functions. its really way completing my need on R at initial level i needed.

I am very much enjoyed the course. However, a lot of dedication is required as a beginner to complete this course.

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

A very demanding course. It took me more than a month to end it but It was worth the effort. I learned a lot.

Each quiz made me learn something new. The final assignment was just the right amount of challenge for a MOOC.

The assignment was quite challenging bu the course overall was very good. The course was structured very well.

Learned a lot, manipulating real data sets to produce "tidy" data sets, suitable for analysis. A great course!

Its really help me a lot to build up my basic concept and now data wrangling is quit bit easy for me.

Thanks :)

Excellent course. I've already used some of the techniques learned here. It's very applicable to those in o
