Not as far as I'm aware. There is draft ggwr() not yet released, which
could possibly be extended, but

Hi Duncan,
For calculating the distance between polygons, there are descriptions of
the calculations for average distance and minimum distance in the
reference below. Although I'm not sure if they're implemented in any R
packages.

I have a follow up question regarding moving old (R <2.4) sp objects to
R 2.4. It is indeed easy using GRASS as an intermediary with spgrass6.
But one of my students has installed GRASS with the QGIS interface
rather than running GRASS under Cygwin. He wanted to do the same.
I tried with him an

Good Day,
I have just loaded R base and an assistant program, "RKWard", onto my
computer only to find that my version is two weeks too old to load the
'sp' file from 'CRAN'. The 'R' version is 2.3.1 and I am wondering where
I might get an older version of 'sp' to run with it. Are there other
