kernel density estimation for univariate data using splancs
...kernel2d(cases1.xy, coord, h0=1000, grd1)
k5000 <- spkernel2d(cases1.xy, coord, h0=5000, grd1)
if (.sp_lt_0.9()) {
df <- AttributeList(list(k1000=k1000, k5000=k5000))
} else {
df <- data.frame(k1000=k1000, k5000=k5000)
}
kernels <- SpatialGridDataFrame(grd1, data=df)
spplot(kernels, checkEmptyRC=FALSE, col.regions=terrain.colors(16), cuts=15)
Using this code, I get NAs for all values of k1000 and k5000. If this did work, can I then subtract the spplots from one another to have the difference between the two sets of cases?
Any advice would be greatly appreciated!
