Dear list,
I have problems to coerce a SpatialGridDataFrame object to a
SpatialPixelDataFrame. I 've calculated a kerneldensity (splancs) and I want
to convert the results from the SpatialGridDataFrame to a
SpatialPixelDataFrame.
My R-code:
library (maptools)
library (splancs)
library (rgdal)
Your df variable should have coordinates in it and in the form of a matrix
or SpatialPoints (from ?SpatialGridDataFrame: points coordinates, either
as numeric matrix or as object of class SpatialPoints-class). Based on the
code you provided, I would guess that you have a few columns to spare, and
You have a typo.
It is SpatialPixelsDataFrame. note the s
