<p>Doctors and dentists accompany survey interviewers in a <a href="https://blogs.cdc.gov/nchs/2013/01/30/217/">mobile medical center</a> that travels the country. While survey researchers read the questionnaires, medical professionals administer laboratory tests and conduct a full medical examination. The blood work and in-person check-up allow epidemiologists to answer questions like, “how many people have diabetes but don’t know they have diabetes?”</p>
<ul>
<li><p>Many tables containing information from the various examinations, generally one row per respondent.</p></li>
<li><p>A complex sample survey designed to generalize to the civilian non-institutionalized U.S. population.</p></li>
<li><p>Released biennially since 1999-2000.</p></li>
<li><p>Administered by the <a href="http://www.cdc.gov/">Centers for Disease Control and Prevention</a>.</p></li>

<p>The R <code>srvyr</code> library calculates summary statistics from survey data, such as the mean, total or quantile using <a href="https://github.com/tidyverse/dplyr/">dplyr</a>-like syntax. <a href="https://github.com/gergness/srvyr">srvyr</a> allows for the use of many verbs, such as <code>summarize</code>, <code>group_by</code>, and <code>mutate</code>, the convenience of pipe-able functions, the <code>tidyverse</code> style of non-standard evaluation and more consistent return types than the <code>survey</code> package. <a href="https://cran.r-project.org/web/packages/srvyr/vignettes/srvyr-vs-survey.html">This vignette</a> details the available features. As a starting point for NHANES users, this code replicates previously-presented examples:</p>
