augment_data_helper

Helper function for <code>check_augment_data_specification()</code>. There should be no need
to ever use this directly in tests. Takes a dataset and returns a list
with three copies of the dataset. Optionally introduces <code>NA</code> values into
the dataset. Useful for checking that tibbles, data frames, and data frames with
rownames are treated equivalently.

internal

Provides a number of testthat tests that can be
used to verify that tidy(), glance() and augment() methods meet
consistent specifications. This allows methods for the same generic to
be spread across multiple packages, since all of those packages can
make the same guarantees to users about returned objects.

augment_data_helper function

<dl><dt>data</dt>
<dd>A data set as a <code>data.frame</code> or <code>tibble</code>.</dd>
<dt>add_missing</dt>
<dd>Whether or not to set some values in <code>data</code> to <code>NA</code>.
When <code>TRUE</code> sets the diagonal elements of <code>data</code> to <code>NA</code> and adds a
row of all <code>NA</code>s to the end of data. This ensures that every column
has missing data. Defaults to <code>FALSE</code>.</dd></dl>

Arguments
