title: Graphing matplotlib with Python code in a R Markdown document
body: <p>Is it possible to use Python matplotlib code to draw graph in RStudio?</p>
  
  <p>e.g. below Python matplotlib code:</p>
  
  <pre><code>import numpy as np
  import matplotlib.pyplot as plt
  
  n = 256
  X = np.linspace(-np.pi,np.pi,n,endpoint=True)
  Y = np.sin(2*X)
  
  plt.plot (X, Y+1, color='blue', alpha=1.00)
  plt.plot (X, Y-1, color='blue', alpha=1.00)
  plt.show()
  </code></pre>
  
  <p>Output graph will be:</p>
  
  <p><a href="https://i.stack.imgur.com/HDlLk.png" rel="noreferrer"><img src="https://i.stack.imgur.com/HDlLk.png" alt="enter image description here"></a></p>
  
  <p>Then I need to write a R Markdown to include these code and generate graph automatically after knitting the markdown.</p>
