title: Installing package e1071
body: <p>I am trying to use 'rfe' function from 'caret':</p>
  <pre><code>lmProfile &lt;- rfe(x=trainData[, 0:(ncol(trainData)-1)], y=trainData$target,
               sizes = subsets,
               rfeControl = ctrl)
  </code></pre>
  <p>but I get the following error:</p>
  <blockquote>
  <p>Error: package e1071 is required</p>
  </blockquote>
  <p>I am running my code in Jupiter Notebook. I've installed both 'caret' and 'e1071' packages:</p>
  <pre><code>install.packages('e1071', dependencies=TRUE)
  install.packages('caret', dependencies = TRUE)
  </code></pre>
  <p>I also tried the following in the terminal:</p>
  <pre><code>conda install -c r r-e1071 
  conda install -c conda-forge r-e1071 
  conda install -c conda-forge/label/gcc7 r-e1071 
  conda install -c conda-forge/label/cf201901 r-e1071 
  conda install -c conda-forge/label/cf202003 r-e1071
  </code></pre>
  <p>I always got the same error message.</p>
  <p>Any suggestions?</p>
