title: Import from a big file only one line at the time in R
body: <p>I have a very big text file that I cannot read in R with <code>read.table()</code> because of its huge size.
  I know that with <code>readLines()</code> function you may specify how many rows you want to import, but I would need to import one line at the time in a for loop, and save it in a new file or store in a vector/list/whatever...</p>
  
  <p>So, something that in <code>python</code> would be:</p>
  
  <pre><code>myfile=open("myfile.txt",mode="r")
  for line in myfile:
      line=line.strip()
      line=line.split("\t")
      print line
  </code></pre>
  
  <p>Is that possible with R?</p>
