ensureVector

Useful for standard argument conversion where a user can input a single
element, but this has to be replicated now n times for a resulting vector or list.

ensureVector function

<dl><dt>x</dt>
<dd>[any] 
Input element.</dd>
<dt>n</dt>
<dd>[<code>integer(1)</code>] 
Desired length.
Default is 1 (the most common case).</dd>
<dt>cl</dt>
<dd>[<code>character</code>*] 
Only do the operation if <code>x</code> inherits from this one of these classes,
otherwise simply let <code>x</code> pass.
Default is <code>NULL</code> which means to always do the operation.</dd>
<dt>names</dt>
<dd>[<code>character</code>*] 
Names for result.
Default is <code>NULL</code>, which means no names.</dd>
<dt>ensure.list</dt>
<dd>[<code>logical(1)</code>] 
Should <code>x</code> be wrapped in a list in any case?
Default is <code>FALSE</code>, i.e., if <code>x</code> is a scalar value, a vector is
returned.</dd></dl>
