[英]How can I implement Nearest Neighbor interpolation method in R?
I have rainfall data that I want to interpolate using different interpolation methods.我有想要使用不同插值方法插值的降雨数据。 I have used gstat
package to calculate IDW and Kriging methods.我已经使用gstat
包来计算 IDW 和 Kriging 方法。
But, I am wondering about any R package and related function that I can use to perform the nearest neighbor method in the R environment.但是,我想知道我可以用来在 R 环境中执行最近邻方法的任何 R 包和相关函数。
Can any one help please?有人可以帮忙吗?
You can use gstat package for this, just set nmin and nmax parameters to 1:您可以为此使用 gstat 包,只需将 nmin 和 nmax 参数设置为 1:
idw(formula = Var ~ 1, locations = spatdat, newdata = raster,
nmax = 1, nmin = 1, force = T, debug.level = -1)
