title: Unable to install car package
body: <p>I am unable to install the car package using version 3.4.4 in r. I keep getting error messages: </p>
  
  <blockquote>
    <p>warning in install.packages : package 'car' not available (for R version 3.4.4) </p>

  <pre><code>install.packages('car', dependencies=TRUE, repos='http://cran.rstudio.com/')
  </code></pre>
