[R-sig-Geo] Regression kriging or kriging with external drift

[Jon Olav Skoien]

Edzer is right, the only important method that supports covariates in 
the intamap package is automap (the other ones are linearVariogram and 
idw). You can set the covariate in the optList-argument to interpolate:
x = interpolate(meuse, meuse.grid, optList = list(formulaString = "zinc 
~ dist"), methodName = "automap")

Cheers,
Jon
