title: Predict on action button click (shinydashboard)
body: <p>I have developed a shiny web app on the IRIS dataset. I want to make the predictions dynamically. I have 4 input boxes, where the user will input the values and based on the model I want to print the predicted value on screen.</p>
  
  <p>This is my code:
  <a href="https://i.stack.imgur.com/3nFex.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3nFex.png" alt="code"></a></p>
  
  <p>On clicking the 'Predict' action button, it is giving me this output:
  <a href="https://i.stack.imgur.com/cXj1x.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cXj1x.png" alt="output"></a></p>
  
  <p>I am not able to understand what it means and where I am wrong in my code. I am new to shiny R. Can anybody please help me fix it?</p>
