The joy and power of functional programming in R

R-Functional-Programming

Workshop Description

This workshop helps you to step up your R skills with functional programming. The purrr package provides easy-to-use tools to automate repeated things in your entire R workflow (e.g., wrangling, modeling, and visualization). The end result is cleaner, faster, more readable and extendable code. I highly recommend you to take this workshop (1) if you still write copy-and-paste code, (2) exclusively rely on for loops for automation, and (3) want to know about the joy and power of R functional programming.

Learning objectives

1. How to use purrr to automate workflow in a cleaner, faster, and more extendable way [Notebook]

2. How to use map2() and pmap() to avoid writing nested loops. [Notebook]

3. How to use map() and glue() to automate creating multiple plots [Notebook]

4. How to use reduce() to automate joining multiple dataframes [Notebook]

5. How to use slowly() and future_ to make automation process either slower or faster [Notebook]

6. How to use safely() and possibly() to make error handling easier [Notebook]

Prerequisites

• Some experience with writing functions in R

Setup

Launch the . Please do so before attending the worskshop as it would take a while (especially, if you do it for the first time).
