title: R studio has different version than shell
body: <p>I am using Ubuntu 16.04 (and will upgrade very soon, yes, but have to solve this issue beforehand).</p>
  <p>When starting R from a bash, I can see the following version:</p>
  <pre><code>&gt; R.version

  <p>When looking at the R version from R-studio, I can see:</p>
  <pre><code>&gt; R.version
