title: R reshape a vector into multiple columns
body: <p>Let's say I have a vector in R as follows: </p>
  
  <pre><code>d&lt;-seq(1,100)
  </code></pre>
  
  <p>I want to reshape this vector into a 10x10 matrix, so that I will have this data instead: </p>
  
  <pre><code>[,1]  [,2]  [,3]  ..  [,10]   
    1      2    3   ..   10
    11    12   13   ..   20
    21    22   23   ..   30
    ..
    91    92   93    ..  100
  </code></pre>
  
  <p>I tried to use reshape function, but it didn't work.  Can someone help please?</p>
