urltools comes with an inbuilt
dataset of public suffixes,
This is used in
suffix_extract to identify the top-level domain
within a particular domain name.
While updates to the dataset will be included in each new package release,
there's going to be a gap between changes to the suffixes list and changes to the package.
Accordingly, the package also includes
suffix_refresh, which generates
and returns a fresh version of the dataset. This can then be passed through
a dataset equivalent in format to
1 2 3 4
## Not run: new_suffixes <- suffix_refresh() ## End(Not run)
