title: Reading a series matrix properly in R
body: <p>I downloaded GSE60341_series_matrix.txt.gz found <a href="ftp://ftp.ncbi.nlm.nih.gov/geo/series/GSE60nnn/GSE60341/matrix/" rel="nofollow noreferrer">here</a> and when I read it into an <strong>R</strong> table as, </p>
  
  <pre><code>x &lt;-read.table("GSE60341_series_matrix.txt", fill = TRUE)
  </code></pre>
  
  <p>I get all the information in rows. In other words I get a matrix of size 
  (42977 rows, and 3 columns), whereas the number of samples should be 1951.
  So ideally, I should get a table of 1951 rows and (some k columns representing each sample).</p>
  
  <p>Opening the text file gets me,</p>

  <p>The information in the categories (<code>lane</code>, <code>stimulation</code>, <code>Sample_title</code>) are concatenated as rows but I want them to be in columns. Can I have a table where rows represent samples and columns represent , say <code>[Sample_title,    stimulation]</code>?</p>
