 <p>I don’t expect this vignette to be help for most srvyr users, it is instead intended for other package developers. An exciting new feature that is easier now that I have reworked srvyr’s non-standard evaluation to match dplyr 0.7+ is that it is now possible for non-srvyr functions to be called from within <code>summarize</code>. This vignette describes some of the inner-workings of summarize so that others can extend srvyr. This is kind of a fiddly part of srvyr, and I don’t expect that many people will want or need to understand it, so this guide is mostly aimed at package authors who already have an understanding of how survey objects work. If you’d like more explanation, please let me know on <a href="https://github.com/gergness/srvyr">github</a>!</p>

 <p>That was just a lot of text, but I think it’s probably easiest just to provide an example. The convey package provides several methods for analysis of inequality using survey data. The svygini function calculates the gini coefficient. Here, we’ll write functions that make a srvyr version <code>survey_gini</code>.</p>
 <p>To distinguish between ungrouped and grouped survey objects, we’ll make a generic. Also note the use of <code>.svy = current_svy()</code> to get the survey object from the current summarize context.</p>
