Hello,
I am trying to do some Kriging incorporating a gradient trend in the data (i.e.
krige(log(zinc)~sqrt(dist),...) based on the method described in
http://r-spatial.sourceforge.net/gallery/ and Bivand's book. I have been having
problems with producing the appropriate grid with a format
Hi,
I have a number of point measurements of soil electrical conductivity
surrounding a large pond (see

create a kriged surface for. Is there any way of excluding distances across the
pond in the variogram

I wish to convert a really complex SpatialPolygonsDataFrame to owin using
MyMask- readOGR(., Mask)
MyMask.owin- as(MyMask, owin)
but I get this error massage in the end
Errore in matrix(FALSE, npoly, npoly) : too many
