title: Matrix display without row and column names?
body: <p>I have this code in R:</p>
  
  <pre><code>seq1 &lt;- seq(1:20)
  mat &lt;- matrix(seq1, 2)
  </code></pre>
  
  <p>and the result is:</p>
  
  <blockquote>
  <pre><code>     [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
  [1,]    1    3    5    7    9   11   13   15   17    19
  [2,]    2    4    6    8   10   12   14   16   18    20
  </code></pre>
  </blockquote>
  
  <p>Does R have an option to suppress the display of column names and row names so that I don't get the [,1] [,2] and so on?</p>
