[R-sig-Geo] Fitting a STvariogram

[alexandre.champendal at unil.ch]

Hello,

I am working with spacetime data of pollution (91 stations, 193 time). 
With the new release of gstat, i was able to compute a good sample 
variogram (thanks :-)).

But now I would like to now if there is a way to visualize our data 
set in order to be able to define a good Space-Time anisotropy !? I 
understand the variable we have to
set: anis = c(p,q,r,s,t), but i am not able to find a good way to find 
the parameters.

How can we do this?

Thanks a lot.

Alexandre
