title: R - could not find function "parenvs"
body: <p><br>
  I'm using R 3.1.2 on Windows 64 bit.<br>
  After installing devtools (version 1.6.1), I couldn't call parenvs() function.<br>
  Here's how I recreate the issue:<br></p>
  
  <blockquote>
    <p>&gt; library(devtools)<br>
    &gt; parenvs(all = TRUE)<br>
    Error: could not find function "parenvs"</p>
  </blockquote>
  
  <p>Did I miss something ?</p>
  
  <p>Thanks<br>
