title: Install Rtools on R version 3.0.2
body: <p>I've installed <em>devtools</em> for R, but when I call the library with:</p>
  
  <pre><code>library(devtools)
  </code></pre>
  
  <p>I get the following output:</p>
  
  <pre><code>WARNING: Rtools is required to build R packages, but is not currently installed.
  Please download and install Rtools 3.1 from http://cran.r-project.org/bin/windows/Rtools/ and then run find_rtools().
  </code></pre>
  
  <p>So I executed the following code:</p>
  
  <pre><code>install.packages("Rtools", repos = "http://cran.r-project.org/bin/windows/Rtools/")
  </code></pre>
  
  <p>And I get the following output:</p>
  
  <pre><code>Installing package into ‘C:~/Documents/R/win-library/3.0’
  (as ‘lib’ is unspecified)
  Warning: unable to access index for repository http://cran.r-project.org/bin/windows/Rtools/bin/windows/contrib/3.0
  Warning message:
  package ‘Rtools’ is not available (for R version 3.0.2)
  </code></pre>
  
  <p>I would appreciate any help that's out there to get Rtools onto my machine so I can call the devtools library.  Thank you!</p>
