title: Caret package findCorrelation() function
body: <p>Hello I am having trouble with the <strong>findCorrelation()</strong> function, Here is my input and the output:</p>
  
  <pre><code>findCorrelation(train, cutoff = .50, verbose = FALSE)
  </code></pre>
  
  <blockquote>
    <p>Error in findCorrelation_exact(x = x, cutoff = cutoff, verbose =
    verbose) :    correlation matrix is not symmetric</p>
  </blockquote>
  
  <p>Does anyone know why this is happening?</p>
