Selective Kriging error
2 messages · kapo coulibaly, Edzer Pebesma
Thanks for forwarding my off-list answer back to the list. Do a library(gstat) demo(examples) and look at the Stratified ordinary kriging example. meuse[meuse$part.a == 0,] is passed to the krige function, meaning a subset of the full meuse dataset. In your case this would be something like yourdata[yourdata$measurementerror == 0,]

I'm doing some interpolations and i would like to know if it is possible
with any of R's geostatistical packages to selectively pick a few points
where I know measurements are "perfect" while the rest of them exhibit
measurement errors?
