title: Reading .h5 file in R
body: <p>I have a '.h5' file and want to extract it using R. </p>
  
  <p>I searched and found <code>rhdf5</code> from <code>BiocManager</code> is used for this purpose. I tried it and I got an error. No matter if I use either 'h5ls' or 'h5read' methods, I always get the same error message below.</p>
  
  <blockquote>
    <p>Error in H5Fopen(file, "H5F_ACC_RDONLY", native = native) : 
      HDF5. File accessibilty. Unable to open file.</p>
  </blockquote>
  
  <pre><code>file_url &lt;- "data/MillionSongSubset/AdditionalFiles/subset_msd_summary_file.h5"
  h5ls(file_url)
  data &lt;- h5read(file_url)
  </code></pre>
  
  <p>I want to extract my '.h5' file either csv or another type in order to use them in R.</p>
