title: How do I install an archived CRAN package
body: <p>I am trying to use the allanvar package which is documented on this <a href="https://www.rdocumentation.org/packages/allanvar/versions/1.1/topics/allanvar" rel="nofollow noreferrer">rdocumentation page</a> and this <a href="https://rdrr.io/cran/allanvar/man/allanvar-package.html" rel="nofollow noreferrer">rdrr.io cran page</a>. When I attempt to load it I get the following</p>
  <pre><code>    &gt; install.packages(&quot;allanvar&quot;)
  Error: package 'allanvar' is not available
  </code></pre>
  <p>Am I doing something wrong, or has it been yanked?</p>
