kriging inside borders
Hi There are a few exemples of kriging inside borders in the geoR tutorials section available at: http://www.est.ufpr.br/geoR Basically you can use polygrid(), althouhg there are other mechanisms available. polygrid() relies on a splancs function internaly Please have a look and if the problem persists please contact me preferelably with some dumpoed workspace and scripts best P.J.

Hello, I'm using geoR package to compute kriging with the function krige.conv() and I used maptools (read.shape () + Map2poly () ) and splancs (borders) packages to include a object of class polylist for the attribute borders. But I've got this message of error when 'borders' is in krige.conv () : krige.conv: there are no prediction locations inside the borders. My polylist is not good? The coordinates seam to be OK when I draw a map with this polylist object. And if I use 'borders' in the contour function : message error is : Error in as.data.frame.default(borders) : can't coerce class "polylist" into a data.frame If someone could help me, thanks a lot!
