[R-sig-Geo] how to fit space-time variogram model

[Benedikt Gräler]

Dear Jason,

using the gstat package (preferably from r-forge), you might want to 
take a look at ?variogramST to calculate a spatio-temporal sample 
variogram surface and demo(stkrige) for fitting and visual inspection 
possibilities.

Kind regards,

  Ben
