idw_interp: Interpolate x to match mask y

In EvolEcolGroup/pastclim: Manipulate Time Series of Climate Reconstructions

Interpolate x to match mask y

Description

Fill in x to match cells available in y, using inverse distance weighted interpolation. Interpolation is fitted using gstat::gstat(); the default parameters for gstat::gstat() are "nmax=7" and "idp=.5", but can be changed by providing arguments to this function (which will be passed to gstat::gstat()). See gstat::gstat() for details on the available parameters and their meaning.

Usage

idw_interp(x, y, nmax = 7, set = list(idp = 0.5), ...)

Arguments

x	the terra::SpatRaster of the variable of interest
y	the terra::SpatRaster the reference mask defining which cells should have values
nmax	the number of nearest observations that should be used for a kriging prediction or simulation, where nearest is defined in terms of the space of the spatial locations (see gstat::gstat() for details)
set	named list with optional parameters to be passed to gstat (only set commands of gstat are allowed, and not all of them may be relevant; see the gstat manual for gstat stand-alone, URL and more details in the gstat::gstat() help page)
...	further parameters to be passed to gstat::gstat()

Value

a terra::SpatRaster of the interpolated version of x
