title: Installing EBImage on Windows 7
body: <p>I'm very new to R. I've tried to install the package EBImage</p>
  <pre><code>&gt; source(&quot;http://bioconductor.org/biocLite.R&quot;)
  &gt; biocLite(&quot;EBImage&quot;)
  </code></pre>
  <p>and got the Warning:</p>
  <blockquote>
  <p>installed directory not writable, cannot update packages 'foreign',
  'lattice', 'Matrix', 'mgcv', 'nlme'</p>
  </blockquote>
  <p>As I've tried to load an image</p>
  <pre><code>&gt; f = system.file(&quot;images&quot;, &quot;C:/aeskuimg/Patterns/Homogenious/h.jpg&quot;, package=&quot;EBImage&quot;)
  &gt; hom = readImage(f)
  </code></pre>
  <p>I've got the error:</p>
  <blockquote>
  <p>Error in readImage(f) : Unable to determine type: Empty filename.</p>
  </blockquote>
  <p>I suspect this is because of the prior warning.</p>
  <p>Is there any solution there?</p>
