how

why

sermon

you should use renv.

commandment

projects should be reproducible.

projects, for the purpose of this workshop, are anything you want to share that isn’t an R package–shiny app, plumber API, quarto doc
reproducibility is a layered, spectral concept rather than a binary
the goal is for the project to be reproducible to the maximum extent possible

how

on repositories

renv: custom R package repositories

get

> options("repos")
$repos
                                         CRAN 
"https://packagemanager.posit.co/cran/latest" 

set:

posit public package manager (p3m)

options(repos = c(CRAN = "https://p3m.dev/cran/latest"))
