transmute.duckplyr_df

This is a method for the <code><a href="https://dplyr.tidyverse.org/reference/mutate.html">dplyr::transmute()</a></code> generic.
See "Fallbacks" section for differences in implementation.
<code>transmute()</code> creates a new data frame containing only the specified computations.
It's superseded because you can perform the same job with <code>mutate(.keep = "none")</code>.

A drop-in replacement for 'dplyr', powered by 'DuckDB' for
performance.  Offers convenient utilities for working with in-memory and
larger-than-memory data while retaining full 'dplyr' compatibility.

transmute.duckplyr_df function

<dl><dt>.data</dt>
<dd>A data frame, data frame extension (e.g. a tibble), or a
lazy data frame (e.g. from dbplyr or dtplyr). See Methods, below, for
more details.</dd>
<dt>...</dt>
<dd>&lt;<code>data-masking</code>&gt; Name-value pairs.
The name gives the name of the column in the output.
The value can be:<ul>
<li>A vector of length 1, which will be recycled to the correct length.</li>
<li>A vector the same length as the current group (or the whole data frame
if ungrouped).</li>
<li><code>NULL</code>, to remove the column.</li>
<li>A data frame or tibble, to create multiple columns in the output.</li>
</ul></dd></dl>

Arguments

There is no DuckDB translation in <code>transmute.duckplyr_df()</code><ul>
<li>with a selection that returns no columns:</li>
</ul>These features fall back to <code><a href="https://dplyr.tidyverse.org/reference/mutate.html">dplyr::transmute()</a></code>, see <code>vignette("fallback")</code> for details.
