title: join multiple matrix in R
body: <p>I want to join several matrix in R, with [48 39 920] dimensions in one single multiarrays [48 39 920 nx], nx is the number of my matrix. For that I am using abind, but I have some problem to get the right dimensions. This is what I am trying:</p>
  
  <pre><code>  matvar &lt;- sapply (1:length(vars), function (i) {
           abind(vars[[i]],along=4)
            })
  </code></pre>
  
  <p>The final dimension for matvar is [1722240  26] , which means 48*39*920...but I want [48 39 920 26]...I would appreciate any suggestion.</p>
  
  <p>Thanks in advance</p>
