<table class="ref-arguments">
<colgroup><col class="name" /><col class="desc" /></colgroup>
<tr>
<th>substances</th>
<td><p>A string or an array of strings with the substance names for
which dose-response data is to be retrieved. Matching is case-sensitive.</p></td>
</tr>
<tr>
<th>experimentator</th>
<td><p>The name of the experimentator whose data is to be used. Default is "<!-- %", -->
which means that data from all experimentators are retrieved.</p></td>
</tr>
<tr>
<th>db</th>
<td><p>The database to be used. Currently, the databases "cytotox", "enzymes"
and "ecotox" of the UFT Department of Bioorganic Chemistry are
supported (default is "cytotox").</p></td>
</tr>
<tr>
<th>celltype</th>
<td><p>Currently, only data for IPC-81, C6, NB4, HeLa, Jurkat and U937 are
supported.</p></td>
</tr>
<tr>
<th>enzymetype</th>
<td><p>Currently, only data for AChE, GR and GST are supported.</p></td>
</tr>
<tr>
<th>organism</th>
<td><p>The organism that was exposed to the chemical. Only important if the database
"ecotox" is used. Defaults to "Vibrio fischeri".</p></td>
</tr>
<tr>
<th>endpoint</th>
<td><p>The endpoint that should be used for selecting the data. Only important if
the database "ecotox" is used. Defaults to "Luminescence".</p></td>
</tr>
<tr>
<th>whereClause</th>
<td><p>With this argument, additional conditions for the SQL query can be set,
e.g. "plate != 710" (i.e. "Do not retrieve data for plate 710"). The
default is 1 (in SQL syntax this means TRUE).</p></td>
</tr>
<tr>
<th>ok</th>
<td><p>With the default value "'ok','no fit'", only data that has been checked and
set to "ok" or "no fit" in the database is retrieved. The argument "no fit"
will result in not using the data for fitting, but it will be plotted.
Another sensible argument would be "'ok','no fit','?'", in order to
additionally retrieve data which has not yet been checked.</p></td>

<h2 class="hasAnchor" id="details"><a class="anchor" href="#details"></a>Details</h2>
<p>The function is currently only used for retrieving data from the
mysql database "cytotox" of the UFT Department of Bioorganic Chemistry.
Access to this database is limited to UFT staff. Additionally to the
installation of the RODBC package, it is required to set up a ODBC data
source with the name "cytotox", using an ODBC driver for mysql, probably
myODBC. Then, under Unix, you can use iodbc or unixodbc for setting up the
respective data source with data source name (DSN) "cytotox". For my
setting using unixodbc, I am using the file <code class="file">/etc/odbcinst.ini</code>
containing:</p><table><tr><td>

</tr><tr><td>
Description </td>
