This code replicates my problem which I would have thought would have

I think splancs and spatial might have their own versions as well. The overlay
function in sp works. I think I found this too slow for what
I am beginning to get a little bit bog eyed with the myriad of options there

I'm sure Roger or someone will come up with exactly what is going on. A couple
