The "new style" way of doing this, using the classes of package sp,
would be reading the shape with readOGR (in package rgdal), and then
selecting by
nw2 = nw[nw$FTEMA>0, ]

I am reading in a shape file using read.shape() I would like to select some of
the polygons in the shape file, depending on data in the att.data ... but for
some (probably simple) reason, it doesn't work.
having read the shape file into the object nw, I would believe that
nw2=nw[nw$att.data$FTE
Thank you for your very interesting responses.
Today I found following ArcGIS 9.3's GWR info in ESRI
site.

Dear Frede
I would not say that the methods discussed in the MBG book should be
refered as "regression kriging".
As far as I understand, the term "regression kriging", despite of all
variations, refer to proposals/algorithms for which predictions are
obtained combining two stages:
1. get predicti
I completely agree with you that this seems the more coherent
statistical modelling approach to these kind of problems. At the time we
did the analysis on /Fulmaris glacialis/, which was 2003, the
corresponding approach was already offered by package geoRglm (using
MCMC; it extends geoR with gl

Anybody interested in these topics should take a look at sections 2.8 "Final notes about
regression-kriging" and "2.2 Local versus localized models" in my lecture notes (I
like to refer to it because it is an open-access material).
I noticed. But is it peer-reviewed?

Dear Jin,
I really think that this list of yours is misleading. I agree, your references
are correct and there are indeed computational differences, however, one should
follow a statistically sound procedure (this includes e.g. GLS estimation of
the regression coefficients, use of proper trans
Sorry for dropping in late in this thread, which I have not followed closely.
Perhaps Paulo Ribeiro can correct me but thinking of geostatistics in terms of
statistical models then I think that the book by Diggle & Ribeiro:
