[GRASSLIST:10491] help with R and GRASS6

[Carlos "Guâno" Grohmann]

Hello list

I've away from R a while, and now I'm struggling with it...
I read Bivand's artile in GRASS-News3, but I dindn't understant exactly how
the data is stored in R.

If I want to make a trend-surface analysis with surf.ls(), I need the x,y
and z coordinates of each point (or pixel), but I don't know how to get
these values

the whole idea is to make TSA, then variogram fitting in the residuals, then
krigging (maybe with gstat or geoR, still haven't decided)

thanks
