Description

Provides a krige (automap, gstat) like interface to Tps (fields)

Usage

doTps(formula, data, newdata, ..., debug.level = 1, addFit = FALSE)

Arguments

formula	A formula to define the dependent and the independent variables, see the documentation of krige.
data	The input data, should be a spatial object which supports coordinates extracting through coordinates()
newdata	A spatial object with the prediction locations.
...	parameters that are passed on to Tps
debug.level	standard value set to 1
addFit	logical, whether or not the output contains the fitted Tps model. See the value section below for more details.

Value

a spatial object with the same class as newdata with the prediction and the variance (NA in this case). The names of the columns match the outcome of the krige function. When addFit equals TRUE the function returns an autoKrige object with two elements: krige_output with the Tps prediction and variance and fit with the fitted Tps model.

Examples

library(sp)
data(meuse)
coordinates(meuse) = ~x+y
data(meuse.grid)
gridded(meuse.grid) = ~x+y

meuse_tps = doTps(zinc~dist, meuse, meuse.grid)
meuse_tps = doTps(zinc~1, meuse, meuse.grid)

summary(meuse_tps$krige_output)
meuse_tps$fit
