The goal of {wontrun} is to test the longevity of old code for the R
programming language by making it easy to run examples from archived
package sources on current versions of packages.
{wontrun} is not available on CRAN, but you can install the
development version like so:
# install.packages("devtools")
devtools::install_github("b-rodrigues/wontrun", ref = "master")This is a basic example which shows you how to solve a common problem:
library(wontrun)
cl <- parallel::detectCores()-2aer_sources <- get_archived_sources("AER")aer_sources

for suggesting using
{callr}which I use in this package. - Thanks to David Hood for suggesting the term code longevity.
- and thanks to everyone on Mastodon for the helpful discussions!
