They are made available when a package is loaded with <code><a href="load_all.html">load_all()</a></code>. </p> <h3>Usage</h3> <pre> # help(topic, package = NULL, ...) # ?e2 # e1?e2 </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>topic</code></td> <td> <p>A name or character string specifying the help topic.</p> </td></tr> <tr valign="top"><td><code>package</code></td> <td> <p>A name or character string specifying the package in which to search for the help topic. If NULL, search all packages.</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>Additional arguments to pass to <code><a href="../../utils/html/help.html">utils::help()</a></code>.</p> </td></tr> <tr valign="top"><td><code>e1</code></td> <td> <p>First argument to pass along to <code style="white-space: pre;">utils::</code>?“.</p> </td></tr> <tr valign="top"><td><code>e2</code></td> <td> <p>Second argument to pass along to <code style="white-space: pre;">utils::</code>?“.</p> </td></tr> </table> <h3>Details</h3> <p>The <code style="white-space: pre;">?</code> function is a replacement for <code><a href="../../utils/html/Question.html">utils::?()</a></code> from the utils package. It will search for help in devtools-loaded packages first, then in regular packages. </p> <p>The <code>help</code> function is a replacement for <code><a href="../../utils/html/help.html">utils::help()</a></code> from the utils package. If <code>package</code> is not specified, it will search for help in devtools-loaded packages first, then in regular packages. If <code>package</code> is specified, then it will search for help in devtools-loaded packages or regular packages, as appropriate. </p> <h3>Examples</h3> <pre> ## Not run: # This would load devtools and look at the help for load_all, if currently # in the devtools source directory. load_all() ?load_all help("load_all") ## End(Not run) # To see the help pages for utils::help and utils::`?`: help("help", "utils") help("?", "utils") ## Not run: # Examples demonstrating the multiple ways of supplying arguments # NB: you can't do pkg <- "ggplot2"; help("ggplot2", pkg) help(lm) help(lm, stats) help(lm, 'stats') help('lm') help('lm', stats) help('lm', 'stats') help(package = stats) help(package = 'stats') topic <- "lm" help(topic) help(topic, stats) help(topic, 'stats') ## End(Not run) </pre> <hr /><div style="text-align: center;">[Package <em>pkgload</em> version 1.3.1 <a href="00Index.html">Index</a>]</div> </body></html>
