+ <h2>Usage</h2>
+ <pre><div>calplot(object, xlim&nbsp;=&nbsp;c("auto", "auto"), ylim&nbsp;=&nbsp;c("auto", "auto"), xlab&nbsp;=&nbsp;"Concentration", ylab&nbsp;=&nbsp;"Response", alpha=0.05, varfunc&nbsp;=&nbsp;NULL)</div></pre>
+
+ <h2>Arguments</h2>
+ <dl>
+ <dt>object</dt>
+ <dd>
+ A univariate model object of class <code><a href='http://www.inside-r.org/r-doc/stats/lm'>lm</a></code> or
+ <code><a href='http://www.inside-r.org/r-doc/MASS/rlm'>rlm</a></code>
+ with model formula <code>y ~ x</code> or <code>y ~ x - 1</code>.
+ </dd>
+ <dt>xlim</dt>
+ <dd>
+ The limits of the plot on the x axis.
+ </dd>
+ <dt>ylim</dt>
+ <dd>
+ The limits of the plot on the y axis.
+ </dd>
+ <dt>xlab</dt>
+ <dd>
+ The label of the x axis.
+ </dd>
+ <dt>ylab</dt>
+ <dd>
+ The label of the y axis.
+ </dd>
+ <dt>alpha</dt>
+ <dd>
+ The error tolerance level for the confidence and prediction bands. Note that this
+ includes both tails of the Gaussian distribution, unlike the alpha and beta parameters
+ used in <code><a href='lod.html'>lod</a></code> (see note below).
+ </dd>
+ <dt>varfunc</dt>
+ <dd>
+ The variance function for generating the weights in the model.
+ Currently, this argument is ignored (see note below).
+ </dd>
+ </dl>
+
+ <div class="Description">
+ <h2>Description</h2>
+
+ <p>Produce graphics of calibration data, the fitted model as well
+ as confidence, and, for unweighted regression, prediction bands.</p>
+
+ </div>
+
+ <div class="Value">
+ <h2>Value</h2>
+
+ <p><dl>
+ A plot of the calibration data, of your fitted model as well as lines showing
+ the confidence limits. Prediction limits are only shown for models from
+ unweighted regression.
+</dl></p>
+
+ </div>
+
+ <div class="Note">
+ <h2>Note</h2>
+
+ <p>Prediction bands for models from weighted linear regression require weights
+ for the data, for which responses should be predicted. Prediction intervals
+ using weights e.g. from a variance function are currently not supported by
+ the internally used function <code><a href='http://www.inside-r.org/r-doc/stats/predict.lm'>predict.lm</a></code>, therefore,
+ <code>calplot</code> does not draw prediction bands for such models.</p>
+
+ <p>It is possible to compare the <code><a href='calplot.lm.html'>calplot</a></code> prediction bands with the
+ <code><a href='lod.html'>lod</a></code> values if the <code>lod()</code> alpha and beta parameters are
+ half the value of the <code>calplot()</code> alpha parameter.</p>
