Dear list,

 

I want to use Kriging with an external drift for a sedimentological dataset
of grain-size that has a linear relation with the depth. 

Am I correct that when I set a 'maxdist' using the krige command, that a
trend for the primary variable (grain-size) is calculated as a local linear
function of the secondary variable (depth)? Is this function thus different
for each interpolation window? 

 

d50.ked.dir50 <- krige(D50F~depth, locations=ds50, newdata=Depth,
model=d50.fit.var.50, nmin=2, nmax=16, maxdist=9000)

 

Thank you for your help.

 

Best regards,

Els Verfaillie
