still have problem with krige and border option
...ead.table("/home/lionel/rwork/poly_test.txt",header=FALSE)
user>polygone<-list(x=border_limite[,1],y=border_limite[,2])
So now I have a list of x,y coordinates to limit my work area.
If I call the function krige with extrap=FALSE like this
user>grid2.krige<-krige(grid2.point,logtab.point,'lz',
logtab.Exp,maxdist=NULL,extrap=FALSE)
[ where grid2.point is a point object to store prediction, logtab.point a
point object containing points data, 'lz' is the variable name in
logtab.point, logtab.Exp is a variogram object ]
all works quiet well, but I am limited...

krige and polygon limit problem
Dear all,
I'm new on R and this mailing list. We work on spatial rainfall estimation
with R and Grass.
We have a problem with the krige function from the sgeostat package. We would
like to limit the estimated area with a polygon limit.
I use a 50 points polygon to describe my work area. The krige function work
quiet well without limit. But if I use this option I have the following error
