Course Overview
Unlock the full power of functional programming in R using the purrr package. This intermediate course teaches you how to write robust, maintainable code by leveraging mapping functions, custom mappers, predicates, and adverbs for complex data structures.
Who Should Enroll?
Ideal for R programmers and data analysts looking to replace repetitive loops with elegant, functional workflows and clean iteration over lists and data frames.
Key Takeaways
- Custom Mappers & Lambdas: Master the flexibility of the .f argument in map functions to iterate over lists, vectors, and data frames.
- Predicates & Adverbs: Utilize functional tools to filter, transform, and control function behaviors efficiently.
- Nested List Manipulation: Extract, discard, and parse elements from nested lists while integrating purrr workflows into custom functions.
About this course
Have you ever been wondering what the purrr description (“A functional programming toolkit for R”) refers to? Then, you’ve come to the right place! This course will walk you through the functional programming part of purrr - in other words, you will learn how to take full advantage of the flexibility offered by the .f in map(.x, .f) to iterate other lists, vectors and data.frame with a robust, clean, and easy to maintain code. During this course, you will learn how to write your own mappers (or lambda functions), and how to use predicates and adverbs. Finally, this new knowledge will be applied to a use case, so that you’ll be able to see how you can use this newly acquired knowledge on a concrete example of a simple nested list, how to extract, keep or discard elements, how to compose functions to manipulate and parse results from this list, how to integrate purrr workflow inside other functions, how to avoid copy and pasting with purrr functional tools.
