unused_import_linter function

<dl><dt>allow_ns_usage</dt>
<dd>Suppress lints for packages only used via namespace.
This is <code>FALSE</code> by default because <code>pkg::fun()</code> doesn't require <code><a href="/link/library(pkg)?package=lintr&version=3.0.2" data-mini-rdoc="lintr::library(pkg)">library(pkg)</a></code>.
You can use <a href="/link/requireNamespace(%22pkg%22)?package=lintr&version=3.0.2" data-mini-rdoc="lintr::requireNamespace("pkg")">requireNamespace("pkg")</a> to ensure a package is installed without loading it.</dd>

<dd>Character vector of packages that are ignored.
These are usually attached for their side effects.</dd></dl>
