For example, <code><a href="../../stats/html/optim.html">stats::optim()</a></code>, <a href="../../base/html/svd.html">svd()</a> and <code><a href="../../akima/html/interp.html">akima::interp()</a></code> produce consistent output, but because they do not have a class attribute, they cannot be handled by S3 dispatch. </p> <p>These functions look at the elements of a list and determine if there is an appropriate tidying method to apply to the list. Those tidiers are themselves are implemented as functions of the form <code style="white-space: pre;">tidy_<function></code> or <code style="white-space: pre;">glance_<function></code> and are not exported (but they are documented!). </p> <p>If no appropriate tidying method is found, throws an error. </p> <h3>Usage</h3> <pre> glance_optim(x, ...) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>x</code></td> <td> <p>A list returned from <code><a href="../../stats/html/optim.html">stats::optim()</a></code>.</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>Additional arguments. Not used. Needed to match generic signature only. <strong>Cautionary note:</strong> Misspelled arguments will be absorbed in <code>...</code>, where they will be ignored. If the misspelled argument has a default value, the default value will be used. For example, if you pass <code>conf.lvel = 0.9</code>, all computation will proceed using <code>conf.level = 0.95</code>. Additionally, if you pass <code>newdata = my_tibble</code> to an <code><a href="reexports.html">augment()</a></code> method that does not accept a <code>newdata</code> argument, it will use the default value for the <code>data</code> argument.</p> </td></tr> </table> <h3>Value</h3> <p>A <code><a href="../../tibble/html/tibble.html">tibble::tibble()</a></code> with exactly one row and columns: </p> <table summary="R valueblock"> <tr valign="top"><td><code>convergence</code></td> <td> <p>Convergence code.</p> </td></tr> <tr valign="top"><td><code>function.count</code></td> <td> <p>Number of calls to 'fn'.</p> </td></tr> <tr valign="top"><td><code>gradient.count</code></td> <td> <p>Number of calls to 'gr'.</p> </td></tr> <tr valign="top"><td><code>value</code></td> <td> <p>Minimized or maximized output value.</p> </td></tr> </table> <h3>See Also</h3> <p><code><a href="reexports.html">glance()</a></code>, <code><a href="../../stats/html/optim.html">stats::optim()</a></code> </p> <p>Other list tidiers: <code><a href="list_tidiers.html">list_tidiers</a></code>, <code><a href="tidy_irlba.html">tidy_irlba</a>()</code>, <code><a href="tidy_optim.html">tidy_optim</a>()</code>, <code><a href="tidy_svd.html">tidy_svd</a>()</code>, <code><a href="tidy_xyz.html">tidy_xyz</a>()</code> </p> <h3>Examples</h3> <pre> f <- function(x) (x[1] - 2)^2 + (x[2] - 3)^2 + (x[3] - 8)^2 o <- optim(c(1, 1, 1), f) </pre> <hr /><div style="text-align: center;">[Package <em>broom</em> version 0.7.0 <a href="00Index.html">Index</a>]</div> </body></html>
