title: R array manipulation
body: <p>In python lists can be sliced like this <code>x[4:-1]</code> to get from the fourth to the last element.</p>
  
  <p>In R something similar can be accomplished for vectors with <code>x[4:length(x)]</code> and for multidimensional arrays with something like <code>x[,,,,4:dim(x)[5],,,]</code>.  Is this more elegant syntax for array slicing for a particular dimension from an element in the middle to the last element?</p>
  
  <p>Thanks    </p>
