[~wunderalbert] would you double check if you set up your Jira account
correctly? I somehow couldn't assign the ticket to you.

> The docstring claims that {{head(n)}} would return a {{Row}} (rather than a
> list of rows) iff n == 1, but that's incorrect.
> Type hints, example, and implementation show that the difference between row
> or list of rows lies in whether n is supplied at all -- if it isn't,
> {{head()}} returns a {{{}Row{}}}, if it is, even if it is 1, {{head(n)}}
> returns a list.

> A suggestion to fix is here: https://github.com/apache/spark/pull/45197
