title: What is the best order of arguments for spatially indexed functions of sf (st_intersects, etc.)?
body: <p>It is explained on <a href="https://www.r-spatial.org/r/2017/06/22/spatial-index.html" rel="nofollow noreferrer">https://www.r-spatial.org/r/2017/06/22/spatial-index.html</a> that &quot;The R tree is constructed on the first argument (<code>x</code>), and used to match all geometries on the second argument (<code>y</code>) of binary functions&quot;. However, it is finally not explained what are the criteria that could guide the user in the choice of the <code>sf</code> object to put in the first argument. Are there some rules of thumb for this choice?</p>
