+<h2>Plot dose-response models</h2>
+
+
+<h3>Description</h3>
+
+<p>
+Produce graphics of dose-response data and dose-response relationships 
+either combined or separately, for one or more substances.
+</p>
+
+
+<h3>Usage</h3>
+
+<pre>
+  drplot(drresults, data, dtype, alpha, path, fileprefix, overlay,
+    postscript, color, colors, fitcolors)
+</pre>
+
+
+<h3>Arguments</h3>
+
+<table summary="R argblock">
+<tr valign="top"><td><code>drresults</code></td>
+<td>
+A data frame as returned from <code><a href="drfit.html">drfit</a></code>.
+</td></tr>
+<tr valign="top"><td><code>data</code></td>
+<td>
+A data frame as returned from <code><a href="drdata.html">drdata</a></code>.  If data is to be
+plotted, the data frame has to contain at least a factor called
+"substance", a vector called "unit" containing the unit used for the dose,
+a column "response" with the response values of the test system normalized
+between 0 and 1, a column "dose" with the numeric dose values and a factor
+called "dosefactor" containing the dose as a factor. If plotting of the data is 
+not required, data can be set to FALSE.
+</td></tr>
+<tr valign="top"><td><code>dtype</code></td>
+<td>
+A string describing if the raw data should be plotted ("raw"), or 
+an error bar should be constructed from the standard deviations of the
+responses at each dose level ("std", default value) or from the confidence
+intervals ("conf"). Of course, dtype only makes a difference, if a valid data
+object has been referenced.
+</td></tr>
+<tr valign="top"><td><code>alpha</code></td>
+<td>
+The confidence level, defaulting to 0.95, only used if dtype "conf" has been
+chosen.
+</td></tr>
+<tr valign="top"><td><code>path</code></td>
+<td>
+The path where graphic files should be put if any are produced. Defaults
+to "./" i.e. the current working directory of R.
+</td></tr>
+<tr valign="top"><td><code>fileprefix</code></td>
+<td>
+A string which will form the beginning of each filename, if graphic files are 
+created. Defaults to "drplot".
+</td></tr>
+<tr valign="top"><td><code>overlay</code></td>
+<td>
+If TRUE, all output will be put into one graph, otherwise a separate graph
+will be created for each substance. In the latter case, on-screen display
+(postscript=FALSE) only works correctly for data plots. Dose-response models
+will all be put into the last graph in this case.
+</td></tr>
+<tr valign="top"><td><code>postscript</code></td>
+<td>
+If TRUE, (a) postscript graph(s) will be created. Otherwise, graphics will be
+displayed with a screen graphics device.
+</td></tr>
+<tr valign="top"><td><code>color</code></td>
+<td>
+If TRUE, a sensible selection of colors will be attempted. If false, everything
+will be drawn in black
+</td></tr>
+<tr valign="top"><td><code>colors</code></td>
+<td>
+This is a vector of colors, defaulting to 1:8, used for plotting the data.
+</td></tr>
+<tr valign="top"><td><code>fitcolors</code></td>
+<td>
+Here you can specify a palette for the colors of the dose-response fits. The 
+default value is "default", which produces rainbow colors.
+</td></tr>
+</table>
+
+<h3>Value</h3>
+
+<table summary="R argblock">
+<tr valign="top"><td><code>results</code></td>
+<td>
+A data frame containing at least one line for each substance. If the data did not
+show a mean response &lt; 0.5 at the highest dose level, the modeltype is set to "none".
+Every successful fit is reported in one line. Parameters of the fitted curves are only
+reported if the fitted EC50 is not higher than the highest dose.</td></tr>
