How to fill NA gaps by IDW using focal (R raster/terra)?

I have a big raster with some NA cells that need to be filled. I want to fill it by Inverse Distance Weighting (IDW), by considering the 9 nearest [valid] cells. I used the idw function from the gstat package, but although it works, it takes ages to…

Universal kriging has a long processing time compared to other kriging methods - R

I have a dataset data_sp with 132 observations containing 9 predictors and 1 response variable. I perform a twenty-fold cross validation, using ordinary kriging and universal kriging. The raster grid100 on which I do my kriging, contains 61124…

Kriging with gstat: including a random effect

I am getting acquainted with gstat and kriging more generally in R. The end goal is to interpolate temperature across my spatial grid, and I want to be able to do so for different time points (average daily temperature over several years). So, I've…

Universal kriging in r. The function predict.gstat return all values as NA

I'm trying to do a universal kriging to get a plot with the predicted values ​​inside a map of a data state. However, after fitting the model and calling the predict.gstat function, the var1.pred values ​​are all NA. It is likely that the error is…

How to perform regression Kriging with R studio using gstat?

I'm struggling with regression kriging in R. I want to interpolate the temperature of a watershed under consideration of elevation, but get always the same error when I want to perform the last step, which is the kriging. I have two data frames, one…

How to get predictions beyond location of sample points with the gstat package?

When using the gstat package to do spatial interpolation using the krige function, I only get results in sample locations. This is not what I was expecting, having read clear explanation of how it works, with a reproducible example here:…

Why is kriging using parallel processing still using memory and not using my processors?

I have a large dataset of measurement over an area. I want to interpolate my data using kriging over my study area. My final output should be a raster/grid. My pc has 8Gb RAM and 4 cores. When I try to use predict() with my fitted variogram, my…

Kriging with gstat : "Covariance matrix singular at location" with predict

I am trying to do an estimation by kriging with gstat, but can never achieve it because of an issue with the covariance matrix. I never have estimates on the locations I want, because they are all skipped. I have the following warning message, for…
