Updating of objects usually takes place in iterative algorithms in which auxiliary quantities associated with the object, and not being optimized over, may change. </p> <h3>Usage</h3> <pre> ## S3 method for class 'modelStruct' needUpdate(object) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>object</code></td> <td> <p>an object inheriting from class <code>"modelStruct"</code>, representing a list of model components, such as <code>corStruct</code> and <code>varFunc</code> objects.</p> </td></tr> </table> <h3>Value</h3> <p>a logical value indicating whether any element of <code>object</code> needs to be updated. </p> <h3>Author(s)</h3> <p>José Pinheiro and Douglas Bates <a href="mailto:bates@stat.wisc.edu">bates@stat.wisc.edu</a></p> <h3>See Also</h3> <p><code><a href="needUpdate.html">needUpdate</a></code> </p> <h3>Examples</h3> <pre> lms1 <- lmeStruct(reStruct = reStruct(pdDiag(diag(2), ~age)), varStruct = varPower(form = ~age)) needUpdate(lms1) </pre> <hr /><div style="text-align: center;">[Package <em>nlme</em> version 3.1-139 <a href="00Index.html">Index</a>]</div> </body></html>
