<h2>Biplots of PLSR and PCR Models.</h2>
<h3>Description</h3>
<p>
Biplot method for <code>mvr</code> objects.
</p>
<h3>Usage</h3>
<pre>
## S3 method for class 'mvr':
biplot(x, comps = 1:2, which = c("x", "y", "scores", "loadings"),
var.axes = FALSE, xlabs, ylabs, main, ...)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
an <code>mvr</code> object.</td></tr>
<tr valign="top"><td><code>comps</code></td>
<td>
integer vector of length two. The components to plot.</td></tr>
<tr valign="top"><td><code>which</code></td>
<td>
character. Which matrices to plot. One of <code>"x"</code> (X
scores and loadings), <code>"y"</code> (Y scores and loadings),
<code>"scores"</code> (X and Y scores) and <code>"loadings"</code> (X and Y loadings).</td></tr>
<tr valign="top"><td><code>var.axes</code></td>
<td>
logical. If <code>TRUE</code>, the second set of points
have arrows representing them.</td></tr>
<tr valign="top"><td><code>xlabs</code></td>
<td>
either a character vector of labels for the first set of
points, or <code>FALSE</code> for no labels. If missing, the row names of
the first matrix is used as labels.</td></tr>
<tr valign="top"><td><code>ylabs</code></td>
<td>
either a character vector of labels for the second set of
points, or <code>FALSE</code> for no labels. If missing, the row names of
the second matrix is used as labels.</td></tr>
<tr valign="top"><td><code>main</code></td>
<td>
character. Title of plot. If missing, a title is
constructed by <code>biplot.mvr</code>.</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
Further arguments passed on to <code>biplot.default</code>.</td></tr>

<h3>Details</h3>
<p>
<code>biplot.mvr</code> can also be called through the <code>mvr</code> plot
method by specifying <code>plottype = "biplot"</code>.

<h3>Examples</h3>
<pre>
data(sensory)
mod <- plsr(Panel ~ Quality, data = sensory)
## Not run:
## These are equivalent
biplot(mod)
plot(mod, plottype = "biplot")
## The four combinations of x and y points:
par(mfrow = c(2,2))
biplot(mod, which = "x") # Default
biplot(mod, which = "y")
biplot(mod, which = "scores")
biplot(mod, which = "loadings")
## End(Not run)
