  <pre><code>              Method      MSE   RMSE    MAE
              Baseline 42674.68 206.58 149.96
     Linear Regression 10738.56 103.63  55.85
         Random forest  4492.47  67.03  37.29
        Neural Network  7650.72  87.47  57.50
  </code></pre>
  
  <p>However, I am not able to obtain this with ggplot or something similar. Can someone help me? </p>
