title: package ‘fpc’ is not available (for R version 3.5.3)
body: <p>package <code>fpc</code> is not available (for R version 3.5.3)</p>
  <p>I have tried a few methods:</p>
  <ol>
  <li><p><code>github_pkgs &lt;- c(&quot;cran/Rstem&quot;)</code><br />
  <code>install_github(github_pkgs)</code></p>
  </li>
  <li><p><code>install.packages(&quot;fpc&quot;, repos= 'http://cran.us.r-project.org')</code></p>
  </li>
  <li><p><code>install.packages(&quot;fpc_2.1-11.2.tar.gz&quot;, repos = NULL)</code></p>
  </li>
  </ol>
  <p>Thank you if you can help me out of this loop...</p>
  <p>None of them works</p>
