title: How to read file in R with column names having brackets?
body: <p>I have one input file. </p>
  
  <p>cat file</p>
  
  <pre><code>      IstCol (ABC) IInd COl (DEF) 
        34           45 
        32           45
  
        &gt; input&lt;-read.table("file",sep="\t",header=TRUE)
        &gt; input
        IstCol..ABC..IInd.COl..DEF.
        1            34           45 
        2             32           45
  </code></pre>
  
  <p>But it does not recognise brackets. What changes need to be made to recognize it?</p>
