<p>WebR makes it possible to run R code in the browser without the need for an R server to execute the code: the R interpreter runs directly on the user’s machine. Several R packages have also been ported for use with webR, and can be loaded in the usual way.</p>

<p>By default, the R code is evaluated and the output is rendered in the <code>document.body</code> of the result page, followed by the plots (rendered as HTML canvas elements).</p>
<p>The evaluation and rendering behavior can be configured by adding a <code>script</code> element in the HTML (markup editor) and setting <code>livecodes.r.config</code>.</p>

<p>The following configurations are supported:</p>
<ul>
<li><code>container</code>: CSS selector of the element in which the R code is rendered. If not specified, the output is rendered in <code>document.body</code>. If set to <code>null</code>, the output is not rendered automatically, and can then be accessed via <code>livecodes.r.output</code> (see below).</li>
<li><code>canvasHeight</code>: a number representing the height of the output canvas in pixels. Defaults to <code>309</code>.</li>
<li><code>canvasWidth</code>: a number representing the width of the output canvas in pixels. Defaults to <code>500</code>.</li>
<li><code>canvasPointSize</code>: a number representing the plots point size. Defaults to <code>12</code>.</li>
<li><code>canvasBackground</code>: a string representing the plots background color. Defaults to <code>"transparent"</code>.</li>
<li><code>autoEvaluate</code>: a boolean indicating whether the R code is evaluated automatically. Defaults to <code>true</code>.</li>
</ul>
<p>In addition, detecting and triggering evaluation can be controlled using:</p>
<ul>
<li><code>livecodes.r.evaluated</code>: a promise that can be awaited to denote when the R code has been evaluated when <code>livecodes.r.config.autoEvaluate</code> is set to <code>true</code>.</li>
<li><code>livecodes.r.run()</code>: an async method that triggers the evaluation of the R code. This is useful when <code>livecodes.r.config.autoEvaluate</code> is set to <code>false</code>. It may take an optional parameter representing the config object (see above)</li>
</ul>
<p>The output and plots can be accessed via:</p>
<ul>
<li><code>livecodes.r.output</code>: a string representing the output of the R code.</li>
<li><code>livecodes.r.plots</code>: an array of HTML canvas elements representing the plots.</li>
</ul>
<p>These are available after the promise <code>livecodes.r.evaluated</code> or that returned by <code>livecodes.r.run()</code> is resolved</p>
