Would like to use .fadeTo elegantly
<p>Here's what I've got far, which works:</p>

<pre><code>var X = $('#myID input:checked').length;
if (X) {
    $('input[name=Save]').show();
} else {
    $('input[name=Save]').hide();
}
</code></pre>

<p>What I'd like to do is write this elegantly using the .fadeTo method.</p>

<pre><code>$('input[name=Save]').fadeTo(Y)
</code></pre>

<p>Where Y=1 if X > 0 AND Y=0 if X = 0.</p>
