These objects are mostly used in the <code>initial</code> function for a self-starting nonlinear regression model, which will be of the <code>selfStart</code> class. </p> <h3>Usage</h3> <pre> sortedXyData(x, y, data) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>x</code></td> <td> <p> a numeric vector or an expression that will evaluate in <code>data</code> to a numeric vector </p> </td></tr> <tr valign="top"><td><code>y</code></td> <td> <p> a numeric vector or an expression that will evaluate in <code>data</code> to a numeric vector </p> </td></tr> <tr valign="top"><td><code>data</code></td> <td> <p> an optional data frame in which to evaluate expressions for <code>x</code> and <code>y</code>, if they are given as expressions </p> </td></tr> </table> <h3>Value</h3> <p>A <code>sortedXyData</code> object. This is a data frame with exactly two numeric columns, named <code>x</code> and <code>y</code>. The rows are sorted so the <code>x</code> column is in increasing order. Duplicate <code>x</code> values are eliminated by averaging the corresponding <code>y</code> values. </p> <h3>Author(s)</h3> <p>José Pinheiro and Douglas Bates</p> <h3>See Also</h3> <p><code><a href="selfStart.html">selfStart</a></code>, <code><a href="NLSstClosestX.html">NLSstClosestX</a></code>, <code><a href="NLSstLfAsymptote.html">NLSstLfAsymptote</a></code>, <code><a href="NLSstRtAsymptote.html">NLSstRtAsymptote</a></code> </p> <h3>Examples</h3> <pre> DNase.2 <- DNase[ DNase$Run == "2", ] sortedXyData( expression(log(conc)), expression(density), DNase.2 ) </pre> <hr /><div style="text-align: center;">[Package <em>stats</em> version 3.6.0 <a href="00Index.html">Index</a>]</div> </body></html>
