kriging shapefiles
3 messages · Leynnard Rey Matillano, Michael Sumner, Paul Hiemstra
It is perhaps easier than you think, see the example in gstat: library(gstat) ?krige After this is run "meuse" is a SpatialPointsDataFrame: coordinates(meuse) = ~x+y Any point shapefile read with readOGR from rgdal (or the alternative functions in maptools) will also be SpatialPointsDataFrames, and so the code will work much the same. To use other kriging functions that perhaps use data.frames, just use as.data.frame(x) to convert a SpatialPointDataFrame to the non-spatial version. Cheers, Mike.

Hi! Im new to R and I need to interpolate a shapefile using kriging. I've been able to plot/read the shapefile using the package maptools or rgdal. I've searched the internet for sample codes but most of the kriging codes that I've found done in R is done using txtfiles or CSVs. ?An example could be of great help. Thanks. ? ? ? ?[[alternative HTML version deleted]]
