Hello,
I am sorry to post this question a second time, but I still got no solution. My
starting point are the local densities from a kernel density estimation (my
object called k1) using the splancs package, now I want to calculate the mean
value for every superimposed polygon (called tsids). T
Here is another example with overlay from the Reimann et al. (2008) book
(this uses a raster map as background - this if often more impressive):
http://www.statistik.tuwien.ac.at/StatDA/R-scripts/page151.html
The code is rather long, but it will give you good ideas what you have to do.

Dear R-sig-geo,
I have just finished with updating the second edition of my lecture notes
that I have used over years for the GEOSTAT summer schools for PhD
students.
A copy of the working draft can be obtained here:

I would like to invite you to read selected

Dear All,
I am new to this list, so apologies if this question has been asked and
answered many times before!
I would like to overlay a bubble chart onto a map so that the bubbles
correspond to particular points on the map. I have the shape file for the map
and the lat long co-ordinates for t
