<h2>Remove All Objects, Except Those Specified</h2>
<h3>Description</h3>
<p>
Remove all objects from the default workspace, except those specified.
</p>
<h3>Usage</h3>
<pre>
keep(..., list = character(0), sure = FALSE)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>...</code></td>
<td>
objects to be kept, specified one by one, quoted or
unquoted.</td></tr>
<tr valign="top"><td><code>list</code></td>
<td>
character vector of object names to be kept.</td></tr>
<tr valign="top"><td><code>sure</code></td>
<td>
whether to perform the removal, otherwise return names of
objects that would have been removed.</td></tr>
</table>
<h3>Details</h3>
<p>
Convenient interface to <code>rm()</code> when removing most objects from
the default workspace.
</p>
<p>
Implemented with a few safety caps: objects whose name starts with a
period ‘<code>.</code>’ are not removed, and <code>sure=TRUE</code> is
required to perform the removal.
</p>
<h3>Value</h3>
<p>
A character vector containing object names, or <code>NULL</code> when
<code>sure</code> is <code>TRUE</code>.</p>
