R-CMD-check Lifecycle: experimental Codecov test coverage CRAN status

Overview

usedthese is a pair of functions to summarise package & function usage in Quarto documents consistent with knitr’s syntax highlighting:

  1. used_here() adds a nicely-rendered summary table of usage to a single document;

  2. used_there() harvests and consolidates the tables created above ready for site-wide analysis.

Example Use Case

Each “little project” on the Quarto website quantumjitter.com focuses on a data science technique or machine learning model to analyse real-world data. At the foot of each of these is a quantified view of the R packages and functions used in the associated code. This is achieved by including used_here() in each Quarto document.

used_there() scrapes all the tables created by used_here() to enable a Favourite Things article on how packages and functions are used across the website.

I personally find this approach makes it easier for me to check for consistency of usage, acknowledge the packages I most need to keep abreast of (or go deeper on), and spot opportunities for updates to the latest and greatest.

When the Tidyverse blog announced changes to dplyr and purrr a quick review of my Favourite Things identified a number of opportunities to try out the exciting new features. For example, dplyr introduced temporary grouping with the .by argument for mutate and amigos. group_by() and ungroup() had been used many times and most of these occurrences could be replaced with the new more concise approach.
