Learning Outcomes
Session 1:
By the end of session 1, participants will be able to…
- understand lists in R and know how to use {purrr} to map functions.
- know what nested loops are and use {magrittr} to extract elements from them.
- be able to create list columns and know how to access the data in them.
Session 2:
By the end of session 2, participants will be able to…
- iteratively loop two or more objects to a function of choice using functions such as
map2(), pmap() and imap().
- recognize the advantages of using {purrr}.
- understand how to extract elements from nested lists to achieve a desired output object class.
- be able to effectively debug their code using multiple {purrr} functions for the debugging process.
- save precious debugging time using e.g.
safely()
This course does not include:
- The {stringr} package, also from the {tidyverse} which helps with splitting and combining strings, manipulating text data and working with regular expressions. Jumping Rivers run a Text Mining in R course which covers {stringr} in detail.
No in-depth coverage of the tidyverse data visualisation package {ggplot2}, see our course on this for more information.
Prior Knowledge
This course assumes basic Tidyverse skills, so having attended Data Wrangling in the Tidyverse or equivalent is necessary. As this course involves iterative programming, basic familiarity with for loops may be helpful. You can learn about for loops on our Programming with R course.
