[R-sig-Geo] How to create generalized spatial weight matrix in R

[Susumu TANIMURA/谷村 晋]

Hi, Roger Bivand,

It is very happy to get response from the author of spdep.  The idea
to use the boundary length proportions from a Voronoi diagram instead
of polygon borders is ingenious for me.

Since  tripack or deldir seems to be related to voronoi diagram in
current library of R, I am going to check these.  Do you have any
other suggestions?

I overlooked the glist. You gave us example in help, so I now know how
to make generalized spatial wight matrix from any other list.

Ummm, I am a Linux user.

Thank you.
