[R] Surfaceplot3D with wireframe

Hi,
I want to make a surface3D plot of a landscape. I have cordinates (x, y, z) recorded with a GPS. The datapoints are not evenly distributed within the rectangular area.

To do a fast 3D plot I used following.

> library(grid)
> library(lattice)
> v <- read.table("clipboard")
> names(v) <- c("x", "y", "z")
> wireframe(z ~ x * y, data = v)

However I just get an empty box with no 3D grid. I have tried with other data and then it usually works. But I cant get it to work with my data. Here is a sample of my data (x, y, z). I think there is something in my data set that wireframe doesnt like. Any ideas?? Are there better commands to use? (I have tried to change the magnitude of the numbers but that doesnt help)

     y               x            z
