title: raster package in R not recognizing a .bil file
body: <p>I normally load .bil files into R using the <code>raster</code> package in R like this:</p>
  
  <pre><code>require(raster)
  require(rgdal)
  
  my.layer&lt;- raster('path/to/file.bil')
  </code></pre>
  
  <p>This general code is working on one of my computers just fine. However, when running this on my cluster I get an error: </p>
  
  <pre><code>Error in .local(.Object, ...) : 
    `/path/to/file.bil' not recognised as a supported file format.
  
  
  Error in .rasterObjectFromFile(x, band = band, objecttype = "RasterLayer",  : 
    Cannot create a RasterLayer object from this file.
  </code></pre>
  
  <p>I can't figure out whats going wrong here. Same error on multiple raster files that load fine on my other computer. I am running R version 3.1.2 and the following package versions:     </p>
  
  <pre><code>rgdal_0.8-16     raster_2.2-31    sp_1.0-15
  </code></pre>
