<table class="ref-arguments">
<colgroup><col class="name" /><col class="desc" /></colgroup>
<tr>
<th>drresults</th>
<td><p>A data frame as returned from <code><a href='drfit.html'>drfit</a></code>.</p></td>
</tr>
<tr>
<th>data</th>
<td><p>A data frame as returned from <code><a href='drdata.html'>drdata</a></code>. 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.</p></td>
</tr>
<tr>
<th>dtype</th>
<td><p>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"). If you don't want to see the data, set it to "none".</p></td>
</tr>
<tr>
<th>alpha</th>
<td><p>The confidence level, defaulting to 0.95, only used if dtype "conf" has been
chosen.</p></td>
</tr>
<tr>
<th>ctype</th>
<td><p>This argument decides if horizontal lines are drawn to show the scatter of
the control values (dose = 0), if there are more than three of them.
Defaults to "none", further allowed values are "std" and "conf" for
displaying the standard deviation of the controls or the confidence
interval for the mean of the controls.</p></td>
</tr>
<tr>
<th>path</th>
<td><p>The path where graphic files should be put if any are produced. Defaults
to "./" i.e. the current working directory of R.</p></td>
</tr>
<tr>
<th>fileprefix</th>
<td><p>A string which will form the beginning of each filename, if graphic files
are created. Defaults to "drplot".</p></td>
</tr>
<tr>
<th>overlay</th>
<td><p>If TRUE, all output will be put into one graph, otherwise a separate graph
will be created for each substance.</p></td>
</tr>
<tr>
<th>xlim</th>
<td><p>The plot limits (min,max) on the dose axis.</p></td>
</tr>
<tr>
<th>ylim</th>
<td><p>The plot limits (min,max) on the response axis.</p></td>
</tr>
<tr>
<th>xlab</th>
<td><p>The axis title for the x axis. Defaults to "Concentration in" <code>unit</code>.</p></td>
</tr>
<tr>
<th>ylab</th>
<td><p>The axis title for the y axis. Defaults to "Normalized response".</p></td>
</tr>
<tr>
<th>axes</th>
<td><p>Specifies if axes should be drawn. Default is TRUE, as in
<code>plot.default</code></p></td>
</tr>
<tr>
<th>frame.plot</th>
<td><p>Specifies if the plot should be framed. Default is TRUE, as in
<code>plot.default</code></p></td>
</tr>
<tr>
<th>postscript</th>
<td><p>If TRUE, (a) postscript graph(s) will be created. Otherwise, and if
the pdf and png arguments are also FALSE, graphics will be
displayed with a screen graphics device.</p></td>
</tr>
<tr>
<th>pdf</th>
<td><p>If TRUE, (a) pdf graph(s) will be created. Otherwise, and if
the postscript, and png arguments are also FALSE, graphics will be
displayed with a screen graphics device.</p></td>
</tr>
<tr>
<th>png</th>
<td><p>If TRUE, (a) png graph(s) will be created. Otherwise, and if the
postscript and pdf arguments are also FALSE, graphics will be displayed
with a screen graphics device.</p></td>
</tr>
<tr>
<th>bw</th>
<td><p>A boolean deciding if the plots will be black and white or not. Default
is TRUE.</p></td>
</tr>
<tr>
<th>pointsize</th>
<td><p>The pointsize used for pdf, png and postscript graphics.</p></td>
</tr>
<tr>
<th>colors</th>
<td><p>This is a vector of colors, defaulting to 1:8, used for plotting the data.</p></td>
</tr>
<tr>
<th>ltys</th>
<td><p>This is a vector of line types for the dose-response models, defaulting to 1:8.</p></td>
</tr>
<tr>
<th>pchs</th>
<td><p>This is a vector of character types for the data. The default uses built-in
characters 1:n with n being the number of substances for which data are plotted
for overlays, or always 1 when no overlay plot is generated.</p></td>
</tr>
<tr>
<th>lpos</th>
<td><p>An optional argument defaulting to "topright" specifying the position
of the legend by being passed to the legend function. See the help for the
legend function for all possiblities.</p></td>
</tr>
<tr>
<th>devoff</th>
<td><p>If set to FALSE, the device will not be closed after creation of an overlay
pdf, png or postscript graph, so texts and other elements can
be added.</p></td>
