I have a little feature request inspired by the new geomapping
function.
Assume a spatial dataset including info from a shape file. Now we can
easily produce maps, but to carry out spatial autocorrelation and
spatial regression analysis we need a spatial weight matrix. Considering
that all the coordinates info is included in the shape files, it would
be nice to be able to recover the coordinates of the centroids of the
units as an extra pair of variables. Then distance-based spatial weight
matrices can be easily constructed by the user with his preferred
formula (or using a contributed function taking the series with the
coordinates as inputs - I can volunteer for that, it'd be at most 10
lines of code :-) )

Hi, I like the idea but at first sight it looks like a job for a
(contributed) hansl function (package). Also, what's the consensus way
of deriving the "centroid" from a polygon?
cheers
