<h2>Extract Scores and Loadings from PLSR and PCR Models</h2>
<h3>Description</h3>
<p>
These functions extract score and loading matrices from fitted
<code>mvr</code> models.
</p>
<h3>Usage</h3>
<pre>
scores(object, ...)
## S3 method for class 'prcomp':
scores(object, ...)
## Default S3 method:
scores(object, ...)
loading.weights(object)
Yscores(object)
Yloadings(object)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>object</code></td>
<td>
a fitted <code>mvr</code> model to extract from.</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
extra arguments, currently not used.</td></tr>
</table>
<h3>Details</h3>
<p>
All functions extract the indicated matrix from the fitted model, and
will work with any object having a suitably named component.
<code>scores</code> also has a method for <code>prcomp</code> objects (their
score component is called <code>x</code>).
<code>loadings</code> is in package <code>stats</code>, and is documented there.
