Hi all,
I've got a question regarding kriging outputs. I have an interpolated dataset which due to the nugget effect contains some negative values as the predictions. I would like to truncate these @ "0", rather than having them as a negative prediction.
I've tried something similar with the meuse data set...

data(meuse.grid) coordinates(meuse.grid) = c("x", "y") gridded(meuse.grid) <- TRUE meuse.grid[["idist"]] = 1 - meuse.grid[["dist"]]
Somewhat arbitrary, but essentially, I'd like to set all "dist" data less than 0.5 to 
"0", and have the rest remain as they are...


meuse.grid[["class"]] = for(i in 1:length(meuse.grid[["dist"]])){
if (meuse.grid[["dist"]]<0.5) {meuse.grid[["class"]]==0} else
{meuse.grid[["class"]]=meuse.grid[["dist"]]}
}

All I've managed to get is the new attribute "class" all filled with 0.

Any insight would be appreciated.
