<td><p>Arguments passed on to <code><ahref='https://ggplot2.tidyverse.org/reference/discrete_scale.html'>ggplot2::discrete_scale</a></code></p><dlclass='dl-horizontal'>
<dt>aesthetics</dt><dd><p>The names of the aesthetics that this scale works with</p></dd>
<dt>scale_name</dt><dd><p>The name of the scale</p></dd>
<dt>palette</dt><dd><p>A palette function that when called with a single integer
argument (the number of levels in the scale) returns the values that
they should take.</p></dd>
<dt>name</dt><dd><p>The name of the scale. Used as the axis or legend title. If
<code>waiver()</code>, the default, the name of the scale is taken from the first
mapping used for that aesthetic. If <code>NULL</code>, the legend title will be
omitted.</p></dd>
<dt>breaks</dt><dd><p>One of:
<ul>
<li><p><code>NULL</code> for no breaks</p></li>
<li><p><code>waiver()</code> for the default breaks computed by the
transformation object</p></li>
<li><p>A character vector of breaks</p></li>
<li><p>A function that takes the limits as input and returns breaks
as output</p></li>
</ul></p></dd>
<dt>labels</dt><dd><p>One of:
<ul>
<li><p><code>NULL</code> for no labels</p></li>
<li><p><code>waiver()</code> for the default labels computed by the
transformation object</p></li>
<li><p>A character vector giving labels (must be same length as <code>breaks</code>)</p></li>
<li><p>A function that takes the breaks as input and returns labels
as output</p></li>
</ul></p></dd>
<dt>limits</dt><dd><p>A character vector that defines possible values of the scale
and their order.</p></dd>
<dt>na.translate</dt><dd><p>Unlike continuous scales, discrete scales can easily show
missing values, and do so by default. If you want to remove missing values
from a discrete scale, specify <code>na.translate = FALSE</code>.</p></dd>
<dt>na.value</dt><dd><p>If <code>na.translate = TRUE</code>, what value aesthetic
value should missing be displayed as? Does not apply to position scales
where <code>NA</code> is always placed at the far right.</p></dd>
<dt>drop</dt><dd><p>Should unused factor levels be omitted from the scale?
The default, <code>TRUE</code>, uses the levels that appear in the data;
<code>FALSE</code> uses all the levels in the factor.</p></dd>
<dt>guide</dt><dd><p>A function used to create a guide or its name. See
<code>guides()</code> for more info.</p></dd>
<dt>super</dt><dd><p>The super class to use for the constructed scale</p></dd>
