title: Cant install blotter package used for quantstrat
body: <p>I'm trying to use the <code>quantstrat</code> package in R. I have uploaded/installed the package using </p>
  
  <pre><code>install.packages("quantstrat", repos="http://R-Forge.R-project.org") 
  </code></pre>
  
  <p>However the once I use </p>
  
  <pre><code>require(quanstrat) 
  </code></pre>
  
  <p>I get the message : </p>
  
  <blockquote>
    <p>Loading required package: quantstrat
    Failed with error:  ‘package ‘blotter’ required by ‘quantstrat’ could not be found’</p>
  </blockquote>
  
  <p>I then use </p>
  
  <pre><code>install.packages("blotter", repos="http://R-Forge.R-project.org") 
  </code></pre>
  
  <p>but get the following message: </p>
  
  <blockquote>
    <p>Package which is only available in source form, and may need compilation of C/C++/Fortran:
      ‘blotter’
      These will not be installed</p>
  </blockquote>
  
  <p>Can anyone offer some suggestion?</p>
