title: Neuralnet package in r with simple structure taking very long time , what is the issue here?
body: <p>I have a problem with <code>neuralnet</code> function from <code>neuralnet</code> package in R. 
  I designed a simple structure with 82 feature as input and only 1 hidden layer with 10 neurons and output is 20 class and I left this line which represent <code>neuralnet</code> function to run above 4 hours and didn't finish ! 
  This is the code : </p>
  
  <pre><code>nn=neuralnet(f, data = train, hidden = 10, err.fct = "sse",threshold = 1, 
               learningrate=.05,rep = 1, linear.output = FALSE)
  </code></pre>
