title: plot() does not work with keras, eclipse and statET
body: <p>I am running <code>keras</code> library from <code>R</code> under eclipse / statET / windows 10. After to fit a model, I am trying to run the following code:</p>
  
  <pre><code>history &lt;- model %&gt;% fit_generator(train_generator, steps_per_epoch = 100, epochs = 30, validation_data = validation_generator, validation_steps = 50)
  
  
  
  jpeg(filename="figuras/history.jpg")
  plot(history)
  dev.off()
  </code></pre>
  
  <p>But no figure is drawn. Nevertheless, if I execute the same sententes above shown in the command line of statET, or I run the whole script from R, it works fine: could someone explain such behaviour?</p>
