Getting data into your statistical analysis system can be one of the most challenging parts of any data science project. Data must be imported and harmonized into a coherent format before any insights can be obtained. You will learn how to get data into R from commonly used formats and harmonizing different kinds of datasets from different sources. If you work in an organization where different departments collect data using different systems and different storage formats, then this course will provide essential tools for bringing those datasets together and making sense of the wealth of information in your organization. This course introduces the Tidyverse tools for importing data into R so that it can be prepared for analysis, visualization, and modeling. Common data formats are introduced, including delimited files, spreadsheets and relational databases, and techniques for obtaining data from the web are demonstrated, such as web scraping and web APIs. In this specialization we assume familiarity with the R programming language. If you are not yet familiar with R, we suggest you first complete R Programming before returning to complete this course.

Excellent. While there were no lectures, and it is possible to simply read the authors' book, having the quizzes makes the difference between just reading and actually learning. Thanks!
RD
Very useful and informative, especially for web related data, e.g. web scraping, json, api's, etc.

Very thorough. A lot of useful content with a couple of level of deepness for if you want to get started, become an expert, or having a guide to back for reference in the future. The final lab was very challenging

Last assingment is a marvelous challenge!
Well presented course.
GOOD STUFF, NUFF SED
Good
Interesting course which helps you develop a data analysis logic in the early stages by codifying the whole process in steps. Really helpful in providing codes for reading (importing) data in R environment. A little bit more practice exercises would made this course perfect.
Muy claro, sencillo y concreto el desarrollo de los temas. Muy interesante la evaluación final.
Cours très instructif et très à niveau.
