title: Read data with space character in R
body: <p>Usually, <code>read.table</code> will solve many data input problems personally. Like this one:</p>
  
  <pre><code>China 2 3
  USA 1 4
  </code></pre>
  
  <p>Sometimes, the data can madden people, like:</p>
  
  <pre><code>Chia 2 3
  United States 3 4
  </code></pre>
  
  <p>So the <code>read.table</code> cannot work, and any assistance is appreciated.</p>
  
  <p>P.S. the format of data file is .dat</p>
