Marius,

I tried setting the 'distance' parameter, but that was less
than satisfactory. One way is to modify the labels appropriately:

  z_at <- seq(2000,10000,2000)
  z_labs <- paste(z_at, "    ", sep="")

which tacks on some spaces, and then plot:

  wireframe(z~grid[,1]*grid[,2],
   aspect=1,
   scales = list(arrows = FALSE,
                 z = list(at = z_at, lab = z_labs)
   ),
   zlab = list("z", hjust = 3),
   ylab = list(rot = -40),
   xlab = list(rot = 30)
)
