title: How to use R with Google Colaboratory?
body: <p>Google Colaboratory supports Python version 2.7 and 3.6</p>
  <p>I saw an example how to use Swift in Colab a while ago.</p>
  <p>Today, I happened to run</p>
  <pre><code>!jupyter-kernelspec list
  </code></pre>
  <p>And found a new kernel: IRkernel</p>
  <pre><code>Available kernels:
    ir         /usr/local/share/jupyter/kernels/ir
    python2    /usr/local/share/jupyter/kernels/python2
    python3    /usr/local/share/jupyter/kernels/python3
    swift      /usr/local/share/jupyter/kernels/swift
  </code></pre>
  <p>Is it now possible to use R in Colab as well? No hassle in installing R kernel?</p>
