Description

Data Science skills are still one of the most in-demand skills on the job market today. Many people see only the fun part of data science, tasks like:  "search for data insight", "reveal the hidden truth behind the data", "build predictive models", "apply machine learning algorithms", and so on. The reality, which is known to most data scientists, is, that when you deal with real data, the most time-consuming operations of any data science project are: "data importing", "data cleaning", "data wrangling", "data exploring" and so on. So it is necessary to have an adequate tool for addressing given data-related tasks. What if I say, there is a freely accessible tool, that falls into the provided description above!


R is one of the most in-demand programming languages when it comes to applied statistics, data science, data exploration, etc. If you combine R with R's collection of libraries called tidyverse, you get one of the deadliest tools, which was designed for data science-related tasks. All tidyverse libraries share a unique philosophy, grammar, and data types. Therefore libraries can be used side by side, and enable you to write efficient and more optimized R code, which will help you finish projects faster.


This course includes several chapters, each chapter introduces different aspects of data-related tasks, with the proper tidyverse tool to help you deal with a given task. Also, the course brings to the table theory related to the topic, and practical examples, which are covered in R. If you dive into the course, you will be engaged with many different data science challenges, here are just a few of them from the course:

  • Tidy data, how to clean your data with tidyverse?

  • Grammar of data wrangling.

  • How to wrangle data with dplyr and tidyr.

  • Create table-like objects called tibble.

  • Import and parse data with readr and other libraries.

  • Deal with strings in R using stringr.

  • Apply Regular Expressions concepts when dealing with strings.

  • Deal with categorical variables using forcats.

  • Grammar of Data Visualization.

  • Explore data and draw statistical plots using ggplot2.

  • Use concepts of functional programming, and map functions using purrr.

  • Efficiently deal with lists with the help of purrr.

  • Practical applications of relational data.

  • Use dplyr for relational data.

  • Tidy evaluation inside tidyverse.

  • Apply tidyverse tools for the final practical data science project.


Course includes:

  • over 25 hours of lecture videos,

  • R scripts and additional data (provided in the course material),

  • engagement with assignments at the end of each chapter,

  • assignments walkthrough videos (where you can check your results).

All being said this makes one of Udemy's most comprehensive courses for data science-related tasks using R and tidyverse.
