peek_vars

peek_data

<ul>
<li><code>peek_vars()</code> returns the vector of names of the variables
currently available for selection.</li>
<li><code>peek_data()</code> returns the whole input vector (only available with
<code>eval_select()</code>).</li>
</ul>Read the <a href="https://tidyselect.r-lib.org/articles/tidyselect.html">Get started</a> for
examples of how to create selection helpers with <code>peek_vars()</code>.
The variable names in a selection context are registered
automatically by <code>eval_select()</code> and <code>eval_rename()</code> for the
duration of the evaluation. <code>peek_vars()</code> is the glue that connects
<a href="/link/selection%20helpers?package=tidyselect&version=1.2.1" data-mini-rdoc="tidyselect::selection helpers">selection helpers</a> to the current selection
context.

A backend for the selecting functions of the 'tidyverse'.  It
makes it easy to implement select-like functions in your own packages
in a way that is consistent with other 'tidyverse' interfaces for
selection.
