<code>win_over()</code> makes it easy to generate the window function specification.
<code>win_absent()</code>, <code>win_rank()</code>, <code>win_recycled()</code>, and <code>win_cumulative()</code>
provide helpers for constructing common types of window functions.
<code>win_current_group()</code> and <code>win_current_order()</code> allow you to access
the grouping and order context set up by <code><a rd-options="=group_by" href="/link/group_by()?package=dbplyr&version=0.0.0.9001&to=%3Dgroup_by" data-mini-rdoc="=group_by::group_by()">group_by()</a></code> and <code><a rd-options="=arrange" href="/link/arrange()?package=dbplyr&version=0.0.0.9001&to=%3Darrange" data-mini-rdoc="=arrange::arrange()">arrange()</a></code>.

A dplyr backend for databases that allows you to work with
remote database tables as if they are in-memory data frames. Basic features
works with any database that has a DBI backend; more advanced features
require SQL translation to be provided by the package author.
