Regression kriging or kriging with external drift
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

Most of the methods in intamap don't support this; IIRC, if any of the methods do, it will be automap, and you could as well use automap::autoKrige directly. On 07/09/2013 11:35 AM, Francesco Carotenuto wrote:
Any suggestions?

Is there a way to perform regression kriging (kriging with external drift) by using the intamap package? If yes, how to set the covariate? Thanks.
