a vector of domains, retrieved through <code><a rd-options="" href="/link/url_parse?package=urltools&version=1.5.0" data-mini-rdoc="urltools::url_parse">url_parse</a></code> or
<code><a rd-options="" href="/link/domain?package=urltools&version=1.5.0" data-mini-rdoc="urltools::domain">domain</a></code>.

<code>host_extract</code> extracts the host from
a vector of domain names. A host isn't the same as a domain - it could be
the subdomain, if there are one or more subdomains. The host of <code>en.wikipedia.org</code>
is <code>en</code>, while the host of <code>wikipedia.org</code> is <code>wikipedia</code>.


A toolkit for handling URLs that so far includes functions for URL
encoding and decoding, parsing, and parameter extraction. All functions are
designed to be both fast and entirely vectorised. It is intended to be
useful for people dealing with web-related datasets, such as server-side
logs, although may be useful for other situations involving large sets of
URLs.
