I would have gone with data.table.utils or data.table.extras to make it absolutely obvious. There is probably some room for a left_join, inner_join, full_join, asof_join wrapper as well (should you look for features)</p>
John MacKintosh<p>I am thinking of creating a package of helper functions for <a href="https://fosstodon.org/tags/rdatatable" class="mention hashtag" rel="tag">#<span>rdatatable</span></a> that makes things like DT[, .N, by][order(-N)] and other common actions a lot easier, and which also works with the new programming interface.</p><p>That particular code for descending sort is something I've written hundreds of times, and I'm fed up of it. Wrapping it into a simple function has been a real boon in my latest project.</p><p>If anyone thinks this package may be a good idea, let me know (somehow) on this post <a href="https://fosstodon.org/tags/RStats" class="mention hashtag" rel="tag">#<span>RStats</span></a></p>
