     These functions modify the view of a data set by allowing
     different sorts of navigation.  Horizontal navigation is always in
     terms of whole columns.  Vertical navigation is in terms of either
     rows or pages.

     lrscroll(v, side = "right", n = 1)
     lrhome(v)
     lrend(v)
     udscroll(v, side = "top", page = FALSE, n = 1)
     udhome(v)
     udend(v)
