  <p>I'm trying to install rgdal_1.2-16.tar.gz for a research project.  I looked <a href="https://stackoverflow.com/questions/12141422/error-gdal-config-not-found">here</a> and did</p>
  <pre><code>sudo apt-get install libgdal1i

  <pre><code>R
  &gt; install.packages('/home/n/Downloads/rgdal_1.2-16.tar.gz', repos = NULL, type=&quot;source&quot;)
  </code></pre>
