Localized krigeST

Dear list,
is there a way restrict the search spatial radius in a spatiotemporal
prediction with gstat::krigeST() (separable covariance models)?
In the help page I can see that further arguments ("...") are passed to the
gstat function, but it seems that e.g. "nmax" is ignored.
not within krigeST, you'd have to write a loop around it that selects the data used for kriging at a particular set of prediction locations/times. things like nmax or radius are obviously not defined in space-time... I'll add sth to the docs in this respect.
In the usual spatial prediction, the parameters for localized kriging needed to be specified upon creation of the gstat object (and not during prediction with krige/precict), so probably something needs to be set when creating a ST*DF? Piero [[alternative HTML version deleted]]
