Different symbols (colors) are used for each object being compared and values corresponding to the same group are joined by a line, to facilitate comparison of fits. If only two coefficients are present, the <code>trellis</code> function <code>xyplot</code> is used; otherwise the <code>trellis</code> function <code>splom</code> is used. </p> <h3>Usage</h3> <pre> ## S3 method for class 'compareFits' pairs(x, subset, key, ...) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>x</code></td> <td> <p>an object of class <code>compareFits</code>.</p> </td></tr> <tr valign="top"><td><code>subset</code></td> <td> <p>an optional logical or integer vector specifying which rows of <code>x</code> should be used in the plots. If missing, all rows are used.</p> </td></tr> <tr valign="top"><td><code>key</code></td> <td> <p>an optional logical value, or list. If <code>TRUE</code>, a legend is included at the top of the plot indicating which symbols (colors) correspond to which objects being compared. If <code>FALSE</code>, no legend is included. If given as a list, <code>key</code> is passed down as an argument to the <code>trellis</code> function generating the plots (<code>splom</code> or <code>xyplot</code>). Defaults to <code>TRUE</code>.</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>optional arguments passed down to the <code>trellis</code> function generating the plots.</p> </td></tr> </table> <h3>Value</h3> <p>Pairwise scatter plots of the values being compared, with different symbols (colors) used for each object under comparison. </p> <h3>Author(s)</h3> <p>José Pinheiro and Douglas Bates </p> <h3>See Also</h3> <p><code><a href="compareFits.html">compareFits</a></code>, <code><a href="plot.compareFits.html">plot.compareFits</a></code>, <code><a href="pairs.lme.html">pairs.lme</a></code>, <code><a href="pairs.lmList.html">pairs.lmList</a></code>, <code><a href="../../lattice/html/xyplot.html">xyplot</a></code>, <code><a href="../../lattice/html/splom.html">splom</a></code> </p> <h3>Examples</h3> <pre> example(compareFits) # cF12 <- compareFits(coef(lmList(Orthodont)), .. lme(*)) plot(cF12) </pre> <hr /><div style="text-align: center;">[Package <em>nlme</em> version 3.1-139 <a href="00Index.html">Index</a>]</div> </body></html>
