[R-sig-Geo] Spatio Temporal Kriging

[Raphael Saldanha]

Hi!

Assuming that you are using the gstat package, looks like that the error occurs when you try to attribute c("Long", "Lat”) to coordinates function.

Try to follow the example from the ?krige function (bellow) with your data:

library(gstat)
library(sp)

data(meuse)
coordinates(meuse) = ~x+y
data(meuse.grid)
gridded(meuse.grid) = ~x+y
m <- vgm(.59, "Sph", 874, .04)

# ordinary kriging:
x <- krige(log(zinc)~1, meuse, meuse.grid, model = m)



Best,

Raphael Saldanha
