domain names have suffixes - common endings that people can or could register domains under. This includes things like ".org", but also things like ".edu.co". A simple Top Level Domain list, as a result, probably won't cut it.
suffix_extract
takes the list of public suffixes,
as maintained by Mozilla (see suffix_dataset
) and
a vector of domain names, and produces a data.frame containing the
suffix that each domain uses, and the remaining fragment.

domains |
a vector of damains, from |
suffixes |
a dataset of suffixes. By default, this is NULL and the function
relies on |
a data.frame of four columns, "host" "subdomain", "domain" & "suffix". "host" is what was passed in. "subdomain" is the subdomain of the suffix. "domain" contains the part of the domain name that came before the matched suffix. "suffix" is, well, the suffix.
suffix_dataset
for the dataset of suffixes.
