The goal of urlchecker is to run the URL checks from R 4.1 in older versions of R and automatically update URLs as needed.
It also uses concurrent requests, so is generally much faster than the URL checks from the tools package.
Install the released version from CRAN
install.packages("urlchecker")
Or the development version from GitHub:
# install.packages("pak")
pak::pak("r-lib/urlchecker")
library(urlchecker)
# `url_check()` will check all URLs in a package, as is done by CRAN when
# submitting a package.
url_check("path/to/pkg")
# `url_update()` will check all URLs in a package, then update any 301
# redirects automatically to their new location.
url_update("path/to/pkg")
