title: How do I cbind elements of a list that are data.frame of the same row size into one large data.frame
body: <p>Say I have a list which have 4 data frames</p>
  
  <pre><code>l&lt;-list()
  l[[1]]&lt;-data.frame(1:10)
  l[[2]]&lt;-data.frame(runif(10))
  l[[3]]&lt;-data.frame(rnorm(10))
  l[[4]]&lt;-data.frame(10:1)
  </code></pre>
  
  <p>how do I cbind these into one data.frame?</p>
  
  <p>When I try cbind I get:</p>
  
  <pre><code>&gt; cbind(l)
       l     
  [1,] List,1
  [2,] List,1
  [3,] List,1
  [4,] List,1
  </code></pre>
