title: Error while using function from car package
body: <p>I'm trying to use a few functions from car package, but while when starting the function (e.g. scatterplotMatrix or bcPower) I get a message "could not find function "scatterplotMatrix""</p>
  
  <p>I I removed and installed package, updated R Studio and I still have the same problem.</p>
  
  <p>A few lines from my code:</p>
  
  <pre class="lang-r prettyprint-override"><code>d &lt;- read.csv2("World.csv") 
  d1 &lt;- d[,c(1,16,25,27,47,56,57,58,59,70)] 
  d1 &lt;- d1[complete.cases(d1), ]  
  scatterplotMatrix(d1[,2:9],smooth = FALSE)
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>Error in scatterplotMatrix(d1[, 2:9], smooth = FALSE) : 
    could not find function "scatterplotMatrix"
  </code></pre>
