[R-sig-Geo] Convert kde object into spatial object

[Michael Sumner]

Here's one way:

library(ks)

data(unicef)
H.scv <- Hscv(x=unicef)
fhat <- kde(x=unicef, H=H.scv)
image(fhat$eval.points[[1]], fhat$eval.points[[2]], fhat$estimate)


library(sp)


spkde <- image2Grid(list(x = fhat$eval.points[[1]], y =
fhat$eval.points[[2]], z = fhat$estimate))
contour(spkde, add = TRUE)
