varFunc

If <code>object</code> is a one-sided formula, it is used as the argument to
 <code>varFixed</code> and the resulting object is returned. Else, if
 <code>object</code> already inherits from class <code>"varFunc"</code>,
 such as all standard &#8216;varClasses&#8217;,
 it is returned unchanged.
