Dear Alok,
Maybe you should consider converting the im data to sp class. Then, you have as
many grids in a
single SpatialGridDataFrame e.g.:
> library(maptools)
> library(rgdal)
> grids <- as(bei.extra[[1]], "SpatialGridDataFrame")
> names(grids)[1] <- "elev"
> grids$grad <- as(bei.extra[[2]],
Thanks Greg for your response:
I want to do what the examples in Spatstat do with regard to the point
and pixel/image data bei and bei.extra.. (bei.extra contains a list of
two image files --elevation and gradient. They plot these two items
(and also take log, I believe)
In my case:

so you get two output polygons. If you do:

Hello Alok,
We really need more details about what you are trying to acheive in order to
help you.
c(X, Y) concatenates the objects X and Y. The result will be a vector. If X
and Y happen to be m x n matrices, the result will be a vector of length 2 *
m * n: probably not what you want.
You can s
Hi,
Thanks for the all the information on kml's and rebuilding gdal which sets me
on a new paths using stuff like VC++, source codes, etc. I started this
'excercise' because we receive more and more kml-files (from Google Earth) of
observers with the outlines of plots and/or observations. But
