title: R - could not find function "ltdl.fix"
body: <p>I'm getting the error:</p>
  <blockquote>
  <p>could not find function &quot;ltdl.fix&quot;</p>
  </blockquote>
  <p>I have installed the update for R and R Studio (2022.07.01) and ltdl.fix doesnt work as the rgr package isn't available?</p>
  <p>Looking for suggestions. Have tried robCompositions and that hasn't worked. Thanks.</p>
