title: R suppress startupMessages from dependency
body: <p>One of my R package's dependencies displays startup messages when loaded.  I would like to suppress these startup messages.</p>
  
  <p>The only fix I found so far was removing the offending package from the Depends: line in my DESCRIPTION file.  Then calling <code>suppressPackageStartupMessages(require("offendingPackage"))</code>    in <code>.onLoad</code> of my package.</p>
  
  <p>I would rather keep the offending package as part of my Depends, but it seems that anything specified in depends is automatically loaded and therefore can't be supressed.</p>
