Yes, that is right.

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
