The R language is widely used among statisticians and data miners for developing statistical software and data analysis.
What You Will Learn
- You will learn analytical skills with one of the most widely used languages in data
Pre-requisites
- Fundamentals of computer programming
- Fundamentals of creating variables
Beginner
Learn the structure of an R solution, and the core of the R programming language.
Building Your First R Analytics Solution
2h 6m
Description
You’ve been given the task of building your next analytics report in R. Your colleague has even shared some R code they think will help. But where do you start? You’re not even sure what to do with the .R file they shared. In this course, Building Your First R Analytics Solution, you’ll see the entire workflow that data professionals use to produce their R analytics solutions. First, you’ll start right at the beginning — setting up your own computer to run R code. Next, you’ll learn how to run, read, and write R code in RStudio. Finally, you'll discover how to organize your work with RStudio projects and how to communicate your work with R Markdown. By the end of the course, you’ll have not only produced a shareable report with R Markdown, you’ll have built your project so that anyone else can recreate the report too. You’ll be using the same tools and workflows as R professionals, and along the way, you’ll start building habits that ensure your analysis is organized, documented, and reproducible.

Creating and Debugging R Programs
2h 1m
Description
Every good developer knows that being able to troubleshoot their code effectively is crucial to being productive. In this course, Creating and Debugging R Programs, you'll gain an understanding of how independently running scripts works within the R platform and how to quickly debug them in the case the need arises. First, you’ll explore the various data types that R provides and learn how to leverage them when processing data. Once you have those understood, you’ll learn how variables are leveraged within functions and how they’re encapsulated within a function’s environment. Finally, you'll discover how to write a non-interactive R script and schedule it to run on multiple platforms. When you’re finished with this course, you’ll have the skills and knowledge to successfully write and run your own independent scripts and troubleshoot running them in a production environment.
