title: /usr/bin/env: RScript: No such file or directory | After recent R-3.0.1. installation.
body: <p>I am a bit lost when dealing with installing and using R. I installed R 3.0.1 from source and did the <strong>./configure, make, make check</strong>, and <strong>make install</strong> as suggested. However I tried running R but it said that R wasn't in the /usr/bin folder. So I then copied the entire R-3.0.1/bin directory into my /usr/bin directory using <strong>cp</strong>. Now I'm getting a few errors regarding /usr/bin/env when trying to use RScript on a hello_world.R script I wrote from the O'Reilly R In a Nutshell book I store in a file hello_world.R the contents are below:</p>
  
  <pre><code>#! /usr/bin/env RScript
  print("Hello World!");
  </code></pre>
  
  <p>Simple enough, but when I try to load it I get the following error:<br> </p>
  
  <pre><code>$ ./hello_world.R
  /usr/bin/env: RScript: No such file or directory
  </code></pre>
  
  <p>I'm not sure if this is a PATH problem or something, but when I search in my /usr/bin directory I do see the RScript file in there along with (R, BATCH, and the others associated with R programming language). Any help is greatly appreciated. Cheers. </p>
