[R-sig-Geo] 3D kriging with gstat

[Prodromos Zanis]

Dear all,

 I want to do kriging with gstat for x,y,z coordinates (latitude, longtitude 
and altitude) to interpolate irregularly distributed temperature station data 
in order to produce a gridded dataset altidude corrected.

where can I find hints or examples on variogram modeling and kriging in 3D with 
gstat?

I look forward for you help. 

thanks and regards,
Prodromos Zanis
