title: How to use Jupyter + SparkR and custom R install
body: <p>I am using a Dockerized image and Jupyter notebook along with SparkR kernel.  When I create a SparkR notebook, it uses an install of Microsoft R (3.3.2) instead of vanilla CRAN R install (3.2.3).</p>
  
  <p>The Docker image I'm using installs some custom R libraries and Python pacakages but I don't explicitly install Microsoft R. Regardless of whether or not I can remove Microsoft R or have it side-by-side, <strong>how I can get my SparkR kernel to use a custom installation of R</strong>?</p>
  
  <p>Thanks in advance</p>
