title: Vignette Table of Contents Missing When Package Published to CRAN
body: <p>I recently released a vignette with version 1.1 of my R package. The Rmd for the vignette can be found <a href="https://github.com/eweine/qqconf/blob/master/qqconf/vignettes/qqconf_introduction.Rmd" rel="nofollow noreferrer">here</a>. When I create the vignette locally, I see author information and the table of contents at the top of the vignette, as expected. However, when I submitted this package to CRAN and the vignette was created <a href="https://cloud.r-project.org/web/packages/qqconf/vignettes/qqconf_introduction.html" rel="nofollow noreferrer">there</a>, I no longer see the table of contents or author information. Does anyone know why this may be happening?</p>
  <p>Thanks.</p>
