title: uncompress a big .gz file
body: <p>I need to uncompress a <code>transactions.gz</code> file downloaded from Kaggle; approximately (2.86 GB), 350 million rows, 11 columns.</p>
  
  <p>I tried on RStudio, windows Vista, 32 bits, RAM: 3 GB:</p>
  
  <pre><code>transactions &lt;- read.table(gzfile("E:/2014/Proyectos/Kaggle/transactions.gz"))
  write.table(transactions, file="E:/2014/Proyectos/Kaggle/transactions.csv")
  </code></pre>
  
  <p>But i receive this error message on the console</p>
  
  <pre><code>&gt; transactions &lt;- read.table(gzfile("E:/2014/Proyectos/Kaggle/transactions.gz"))
  Error: cannot allocate vector of size 64.0 Mb
  &gt; write.table(transactions, file="E:/2014/Proyectos/Kaggle/transactions.csv")
  Error: cannot allocate vector of size 64.0 Mb
  </code></pre>
  
  <p>I checked this case, but it didn't work for me: <a href="https://stackoverflow.com/questions/5764499/decompress-gz-file-using-r">Decompress gz file using R</a></p>
  
  <p>I would appreciate any suggestions.</p>
