+<h2>Plot calibration graphs</h2>
+
+
+<h3>Description</h3>
+
+<p>
+Produce graphics of calibration data, the fitted model as well
+as prediction and confidence intervals.
+</p>
+
+
+<h3>Usage</h3>
+
+<pre>
+  calplot(x,y,intercept=FALSE,measurand="substance x",xunit="mg/L",yunit="Area",level=0.95)
+</pre>
+
+
+<h3>Arguments</h3>
+
+<table summary="R argblock">
+<tr valign="top"><td><code>x</code></td>
+<td>
+A vector of x values.
+</td></tr>
+<tr valign="top"><td><code>y</code></td>
+<td>
+A vector of y values.
+</td></tr>
+<tr valign="top"><td><code>intercept</code></td>
+<td>
+A boolean describing if the calibration curve is to be forced
+through zero.
+</td></tr>
+<tr valign="top"><td><code>measurand</code></td>
+<td>
+The name of what is being measured as a character vector.
+</td></tr>
+<tr valign="top"><td><code>xunit</code></td>
+<td>
+The unit of the given values on the x axis as a character vector.
+</td></tr>
+<tr valign="top"><td><code>yunit</code></td>
+<td>
+The unit of the y axis as a character vector. Defaults to "Area".
+</td></tr>
+<tr valign="top"><td><code>level</code></td>
+<td>
+The confidence level of the confidence and prediction bands. Defaults to
+0.95.
+</td></tr>
+</table>
+
+<h3>Value</h3>
+
+<p>
+A linear model object for y ~ x.  You will also get a plot of the calibration
+data, of your fitted model as well as lines showing the confidence limits and
+the prediction limits.</p>
