title: Pre-caching Shiny renderCachedPlot automatically
body: <p>I am wondering if it is possible to pre-cache a set of initial inputs for renderCachedPlot. I cannot figure out how to do this, I know that renderCachedPlot uses digest to generate the hash but it also uses a set of height + weight in a way that I can't figure out. And I can't figure it out from looking at the source code either.</p>
  <p>My exact question was also asked here (with no solution):</p>
