Footnotes

1. Packages are automatically loaded in each R session so you don't need to install or import; however within box modules these packages need to be imported with box::use(). ↩

2. All tidyverse packages can be installed using installed using install.packages("tidyverse") but core tidyverse packages can also be imported together using library("tidyverse"). For box modules refer to each specific package in the box::use() statement instead. ↩
