mode.</p></dd>
|
|
|

|
|
<dt id="arg-transform">transform<a class="anchor" aria-label="anchor" href="#arg-transform"></a></dt>
|
|
<dd><p>A function that takes four arguments: <code>value</code>,
|
|
<code>session</code>, <code>name</code>, and <code>...</code> (for future-proofing). This
|
|
function will be invoked each time a value is returned from <code>func</code>,
|
|
and is responsible for changing the value into a JSON-ready value to be
|
|
JSON-encoded and sent to the browser.</p></dd>

|
|

<dt id="arg-outputfunc">outputFunc<a class="anchor" aria-label="anchor" href="#arg-outputfunc"></a></dt>

<dd><p>The UI function that is used (or most commonly used) with
|
|
this render function. This can be used in R Markdown documents to create
|
|
complete output widgets out of just the render function.</p></dd>
|
|
|
|
|
|
<dt id="arg-outputargs">outputArgs<a class="anchor" aria-label="anchor" href="#arg-outputargs"></a></dt>
|
|
<dd><p>A list of arguments to pass to the <code>uiFunc</code>. Render
|
|
functions should include <code>outputArgs = list()</code> in their own parameter list,
|
|
and pass through the value to <code>markRenderFunction</code>, to allow app authors to
|
|
customize outputs. (Currently, this is only supported for dynamically
|
|
generated UIs, such as those created by Shiny code snippets embedded in R
|
|
Markdown documents).</p></dd>
|
|

|

<dt id="arg-cachehint">cacheHint<a class="anchor" aria-label="anchor" href="#arg-cachehint"></a></dt>
|
|
<dd><p>One of <code>"auto"</code>, <code>FALSE</code>, or some other information to
|
|
identify this instance for caching using <code><a href="bindCache.html">bindCache()</a></code>. If <code>"auto"</code>, it
|
|
will try to automatically infer caching information. If <code>FALSE</code>, do not
|
|
allow caching for the object. Some render functions (such as <a href="renderPlot.html">renderPlot</a>)
|
|
contain internal state that makes them unsuitable for caching.</p></dd>

<dt id="arg-cachewritehook">cacheWriteHook<a class="anchor" aria-label="anchor" href="#arg-cachewritehook"></a></dt>
|
|
<dd><p>Used if the render function is passed to <code><a href="bindCache.html">bindCache()</a></code>.
|
|
This is an optional callback function to invoke before saving the value
|
|
from the render function to the cache. This function must accept one
|
|
argument, the value returned from <code>renderFunc</code>, and should return the value
|
|
to store in the cache.</p></dd>

<dt id="arg-cachereadhook">cacheReadHook<a class="anchor" aria-label="anchor" href="#arg-cachereadhook"></a></dt>
|
|
<dd><p>Used if the render function is passed to <code><a href="bindCache.html">bindCache()</a></code>.
|
|
This is an optional callback function to invoke after reading a value from
|
|
the cache (if there is a cache hit). The function will be passed one
|
|
argument, the value retrieved from the cache. This can be useful when some
|
|
side effect needs to occur for a render function to behave correctly. For
|
|
example, some render functions call <code><a href="createWebDependency.html">createWebDependency()</a></code> so that Shiny
|
|
is able to serve JS and CSS resources.</p></dd>

|
|
your quosure, it is recommended to use <code><a href="https://rlang.r-lib.org/reference/defusing-advanced.html" class="external-link">rlang::enquo0()</a></code> to not unquote
|
|
the object too early. See <code><a href="https://rlang.r-lib.org/reference/defusing-advanced.html" class="external-link">rlang::enquo0()</a></code> for more details.</p></dd>

|
|
<h2>Details</h2>
|
|
<p>To implement a custom <code>renderXXX()</code> function, essentially 2 things are needed:</p><ol><li><p>Capture the user's reactive expression as a function.</p><ul><li><p>New <code>renderXXX()</code> functions can use <code>quoToFunction()</code> for this, but
|
|
already existing <code>renderXXX()</code> functions that contain <code>env</code> and <code>quoted</code>
|
|
parameters may want to continue using <code>installExprFunction()</code> for better
|
|
legacy support (see examples).</p></li>
|
|
</ul></li>
|
|
<li><p>Flag the resulting function (from 1) as a Shiny rendering function and
|
|
also provide a UI container for displaying the result of the rendering
|
|
function.</p><ul><li><p><code>createRenderFunction()</code> is currently recommended (instead of
|
|
<code><a href="markRenderFunction.html">markRenderFunction()</a></code>) for this step (see examples).</p></li>
