arg_check_influence_plot function

<dl><dt>model</dt>
<dd>A fitted model object from the
<code><a href="/link/lm?package=api2lm&version=0.2" data-mini-rdoc="api2lm::lm">lm</a></code> function.</dd>
<dt>id_n</dt>
<dd>The number of points to identify with labels
with respect to largest absolute criterion. The default
is <code>3</code> labels.</dd>
<dt>add_reference</dt>
<dd>A logical value indicating whether a
reference line should be added. The default is
<code>TRUE</code>.</dd>
<dt>alpha</dt>
<dd>The default quantile used for the horizontal
reference lines. The default is 0.05. See Details.</dd>
<dt>size</dt>
<dd>A numeric vector of length 2 that provides
guidelines for the size of the points.</dd>
<dt>text_arglist</dt>
<dd>Additional arguments passed to the
<code><a href="/link/text?package=api2lm&version=0.2" data-mini-rdoc="api2lm::text">text</a></code> function, which is used to
display the points that are identified.</dd>
<dt>abline_arglist</dt>
<dd>A named list specifying additional
arguments passed to the <code><a href="/link/abline?package=api2lm&version=0.2" data-mini-rdoc="api2lm::abline">abline</a></code>
function for the horizontal reference line added to the
plot.</dd>
<dt>extendrange_f</dt>
<dd>Positive number(s) specifying the
fraction by which the range of the residuals should be
extended using the <code><a href="/link/extendrange?package=api2lm&version=0.2" data-mini-rdoc="api2lm::extendrange">extendrange</a></code>
function. If longer than one, <code>f[1]</code> is used on
the left and <code>f[2]</code> on the right.</dd></dl>
