Hello yet again:
I have a little data set that I want to get a variogram for. However, I keep
getting an error.
> str(z1.df)
Formal class 'SpatialPointsDataFrame' [package "sp"] with 5 slots
..@ data :'data.frame': 5 obs. of 1 variable:
.. ..$ x: num [1:5] 1.4228 0.0275 -0.3738 0.2812 0.2328
..@ coords.nrs : int [1:2] 2 3
..@ coords : num [1:5, 1:2] 146.9 133.8 -85.8 -99.9 -91.1 ...
.. ..- attr(*, "dimnames")=List of 2
.. .. ..$ : NULL
.. .. ..$ : chr [1:2] "lon" "lat"
..@ bbox : num [1:2, 1:2] -99.9 -31.3 146.9 38.3
.. ..- attr(*, "dimnames")=List of 2
.. .. ..$ : chr [1:2] "lon" "lat"
.. .. ..$ : chr [1:2] "min" "max"
..@ proj4string:Formal class 'CRS' [package "sp"] with 1 slots
.. .. ..@ projargs: chr NA
> variogram(z1.df)
Error in variogram.default(z1.df) :
argument object and locations should be lists

Does this make any sense, please?
Thanks,
