Extract unique elements and sort them

A collection of functions for analyzing data typically collected
or used by behavioral scientists. Examples of the functions include
a function that compares groups in a factorial experimental design,
a function that conducts (robust) two-way analysis of variance (ANOVA),
and a function that cleans a data set generated by Qualtrics surveys.
Some of the functions will require installing additional package(s).
Such packages and other references are cited within the section
describing the relevant functions. Many functions in this package
rely heavily on these two popular R packages:
Dowle et al. (2021) <https://CRAN.R-project.org/package=data.table>.
Wickham et al. (2021) <https://CRAN.R-project.org/package=ggplot2>.

su function

<dl><dt>x</dt>
<dd>a vector or a data frame or an array or NULL.</dd>
<dt>na.last</dt>
<dd>an argument to be passed onto the 'sort' function
(in base R) for controlling the treatment of NA values.
If <code>na.last = TRUE</code>, NA values in the data are put last;
if <code>na.last = FALSE</code>, NA values are put first;
if <code>na.last = NA</code>, NA values are removed.
By default, <code>na.last = TRUE</code></dd>
<dt>decreasing</dt>
<dd>logical. Should the sort be increasing or decreasing?
An argument to be passed onto the 'sort' function (in base R).
By default, <code>decreasing = FALSE</code></dd></dl>

Arguments

su: Sorted unique values — su
